Chapter 7. Growing and Developing
- Review the physical and cognitive changes that accompany early and middle adulthood.
Until the 1970s, psychologists tended to treat adulthood as a single developmental stage, with few or no distinctions made between the various periods that we pass through between adolescence and death. Present-day psychologists realize, however, that physical, cognitive, and emotional responses continue to develop throughout life, with corresponding changes in our social needs and desires. Thus the three stages of early adulthood, middle adulthood, and late adulthood each have their own physical, cognitive, and social challenges.
In this section, we will consider the development of our cognitive and physical aspects that occur during early adulthood and middle adulthood — roughly the ages between 25 and 45 and between 45 and 65, respectively. These stages represent a long period of time — longer, in fact, than any of the other developmental stages — and the bulk of our lives is spent in them. These are also the periods in which most of us make our most substantial contributions to society, by meeting two of Erik Erikson’s life challenges: we learn to give and receive love in a close, long-term relationship, and we develop an interest in guiding the development of the next generation, often by becoming parents.
Psychology in Everyday Life: What Makes a Good Parent?
One thing that you may have wondered about as you grew up, and which you may start to think about again if you decide to have children yourself, concerns the skills involved in parenting. Some parents are strict, others are lax; some parents spend a lot of time with their kids, trying to resolve their problems and helping to keep them out of dangerous situations, whereas others leave their children with nannies or in day care. Some parents hug and kiss their kids and say that they love them over and over every day, whereas others never do. Do these behaviours matter? And what makes a “good parent”?
We have already considered two answers to this question, in the form of what all children require: (a) babies need a conscientious mother who does not smoke, drink, or use drugs during her pregnancy, and (b) infants need caretakers who are consistently available, loving, and supportive to help them form a secure base. One case in which these basic goals are less likely to be met is when the mother is an adolescent. Adolescent mothers are more likely to use drugs and alcohol during their pregnancies, to have poor parenting skills in general, and to provide insufficient support for the child (Ekéus, Christensson, & Hjern, 2004). As a result, the babies of adolescent mothers have higher rates of academic failure, delinquency, and incarceration in comparison to children of older mothers (Moore & Brooks-Gunn, 2002).
Normally, it is the mother who provides early attachment, but fathers are not irrelevant. In fact, studies have found that children whose fathers are more involved tend to be more cognitively and socially competent, more empathetic, and psychologically better adjusted, compared with children whose fathers are less involved (Rohner & Veneziano, 2001). In fact, Amato (1994) found that, in some cases, the role of the father can be as important as, or even more important than, that of the mother in the child’s overall psychological health and well-being. Amato concluded, “Regardless of the quality of the mother-child relationship, the closer adult offspring were to their fathers, the happier, more satisfied, and less distressed they reported being” (p. 1039).
As the child grows, parents take on one of four types of parenting styles — parental behaviours that determine the nature of parent-child interactions and that guide their interaction with the child. These styles depend on whether the parent is more or less demanding and more or less responsive to the child (see Figure 7.9, “Parenting Styles”). Authoritarian parents are demanding but not responsive. They impose rules and expect obedience, tending to give orders (“Eat your food!”) and enforcing their commands with rewards and punishment, without providing any explanation of where the rules came from except “Because I said so!” Permissive parents, on the other hand, tend to make few demands and give little punishment, but they are responsive in the sense that they generally allow their children to make their own rules. Authoritative parents are demanding (“You must be home by curfew”), but they are also responsive to the needs and opinions of the child (“Let’s discuss what an appropriate curfew might be”). They set rules and enforce them, but they also explain and discuss the reasons behind the rules. Finally, rejecting-neglecting parents are undemanding and unresponsive overall.
Many studies of children and their parents, using different methods, measures, and samples, have reached the same conclusion — namely, that authoritative parenting, in comparison to the other three styles, is associated with a wide range of psychological and social advantages for children. Parents who use the authoritative style, with its combination of demands on the children as well as responsiveness to the children’s needs, have kids who show better psychological adjustment, school performance, and psychosocial maturity compared with the kids of parents who use the other styles (Baumrind, 1996; Grolnick & Ryan, 1989).
On the other hand, there are cultural differences in parenting styles. In a study comparing parenting styles in Canada, France, and Italy, Michael Claes and colleagues at the University of Montreal found Canadian parents to be the most tolerant, having fewer rules and disciplinary actions. Canadian mothers and fathers were seen as less punitive, less coercive, and more tolerant than French and Italian mothers. The French were found to parent in a moderate style. French fathers, however, were perceived by teens as emotionally distant, rigid, and prone to intergenerational conflict. French mothers, for their part, were reported to foster closer bonds as their children grew into adolescence (Claes et al., 2011).
In all three countries, teens experienced a gradual decrease in behavioural control between the ages of 11 and 19: fathers and mothers reduced requirements and disciplinary constraints. “Our study found parental control is dictated by social codes and culture-specific values, which promote certain parental practices and proscribe others,” says Dr. Claes, noting that Canadian parents value a democratic conception of education that promotes independence and negotiation, while European parents, especially Italians, advocate for obligations and respect for parental authority (Science Daily, 2010).
Despite the fact that different parenting styles are differentially effective overall, every child is different and parents must be adaptable. Some children have particularly difficult temperaments, and these children require more parenting. Because these difficult children demand more parenting, the behaviours of the parents matter more for the children’s development than they do for other, less demanding children who require less parenting overall (Pluess & Belsky, 2010). These findings remind us how the behaviour of the child can influence the behaviour of the people in his or her environment.
Although the focus is on the child, the parents must never forget about each other. Parenting is time-consuming and emotionally taxing, and the parents must work together to create a relationship in which both mother and father contribute to the household tasks and support each other. It is also important for the parents to invest time in their own intimacy, as happy parents are more likely to stay together, and divorce has a profoundly negative impact on children, particularly during and immediately after the divorce (Burt, Barnes, McGue, & Iacono, 2008; Ge, Natsuaki, & Conger, 2006).
Physical and Cognitive Changes in Early and Middle Adulthood
Compared with the other stages, the physical and cognitive changes that occur in the stages of early and middle adulthood are less dramatic. As individuals pass into their 30s and 40s, their recovery from muscular strain becomes more prolonged, and their sensory abilities may become somewhat diminished, at least when compared with their prime years, during the teens and early 20s (Panno, 2004). Visual acuity diminishes somewhat, and many people in their late 30s and early 40s begin to notice that their eyes are changing and they need eyeglasses. Adults in their 30s and 40s may also begin to suffer some hearing loss because of damage to the hair cells (cilia) in the inner ear (Lacher-Fougëre & Demany, 2005). And it is during middle adulthood that many people first begin to suffer from ailments such as high cholesterol and high blood pressure as well as low bone density (Shelton, 2006). Corresponding to changes in our physical abilities, our cognitive and sensory abilities also seem to show some, but not dramatic, decline during this stage.
The stages of both early and middle adulthood bring about a gradual decline in fertility, particularly for women. Eventually, women experience menopause, the cessation of the menstrual cycle, which usually occurs at around age 50. Menopause occurs because of the gradual decrease in the production of the female sex hormones estrogen and progesterone, which slows the production and release of eggs into the uterus. Women whose menstrual cycles have stopped for 12 consecutive months are considered to have entered menopause (Minkin & Wright, 2004).
Researchers have found that women’s responses to menopause are social as well as physical, and that they vary substantially between both individuals and cultures. Within individuals, some women may react more negatively to menopause, worrying that they have lost their femininity and that their final chance to bear children is over, whereas other women may regard menopause more positively, focusing on the new freedom from menstrual discomfort and unwanted pregnancy. In Western cultures such as in Canada, women are likely to see menopause as a challenging and potentially negative event, whereas in India, where older women enjoy more social privileges than do younger ones, menopause is more positively regarded (Avis & Crawford, 2008).
Menopause may have evolutionary benefits. Infants have better chances of survival when their mothers are younger and have more energy to care for them, and the presence of older women who do not have children of their own to care for (but who can help out with raising grandchildren) can be beneficial to the family group. Also consistent with the idea of an evolutionary benefit of menopause is that the decline in fertility occurs primarily for women, who do most of the child care and who need the energy of youth to accomplish it. If older women were able to have children, they might not be as able to effectively care for them. Most men never completely lose their fertility, but they do experience a gradual decrease in testosterone levels, sperm count, and speed of erection and ejaculation.
Social Changes in Early and Middle Adulthood
Perhaps the major marker of adulthood is the ability to create an effective and independent life. Whereas children and adolescents are generally supported by parents, adults must make their own living and must start their own families. Furthermore, the needs of adults are different from those of younger persons.
Even though the timing of the major life events that occur in early and middle adulthood varies substantially among individuals, the events nevertheless tend to follow a general sequence, known as a social clock. The social clock refers to the culturally preferred “right time” for major life events, such as moving out of the childhood house, getting married, and having children. People who do not appear to be following the social clock (e.g., young adults who still live with their parents, individuals who never marry, and couples who choose not to have children) may be seen as unusual or deviant, and they may be stigmatized by others (DePaulo, 2006; Rook, Catalano, & Dooley, 1989).
Although they are doing it later, on average, than they did even 20 or 30 years ago, most people do eventually marry. Marriage is beneficial to the partners, both in terms of mental health and physical health. People who are married report greater life satisfaction than those who are not married and also suffer fewer health problems (Gallagher & Waite, 2001; Liu & Umberson, 2008).
Divorce is more common now than it was 50 years ago. Fluctuating between 35% and 42%, the proportion of marriages projected to end in divorce has remained relatively stable during the last 20 years in Canada. In 2008, 40.7% of marriages were projected to end in divorce before the 30th wedding anniversary (Statistics Canada, 2011), although about three-quarters of people who divorce will remarry. Most divorces occur for couples in their 20s, because younger people are frequently not mature enough to make good marriage choices or to make marriages last. Marriages are more successful for older adults and for those with more education (Goodwin, Mosher, & Chandra, 2010).
Parenthood also involves a major and long-lasting commitment, and one that can cause substantial stress on the parents. The time and finances invested in children create stress, which frequently results in decreased marital satisfaction (Twenge, Campbell, & Foster, 2003). This decline is especially true for women, who bear the larger part of the burden of raising the children and taking care of the house, despite the fact they increasingly also work and have careers.
Despite the challenges of early and middle adulthood, the majority of middle-aged adults are not unhappy. These years are often very satisfying, as families have been established, careers have been entered into, and some percentage of life goals has been realized (Eid & Larsen, 2008).
- It is in early and middle adulthood that muscle strength, reaction time, cardiac output, and sensory abilities begin to decline.
- One of the key signs of aging in women is the decline in fertility, culminating in menopause, which is marked by the cessation of the menstrual period.
- The different social stages in adulthood, such as marriage, parenthood, and work, are loosely determined by a social clock, a culturally recognized time for each phase.
Exercises and Critical Thinking
- Compare your behaviour, values, and attitudes regarding marriage and work to the attitudes of your parents and grandparents. In what way are your values similar? In what ways are they different?
- Draw a timeline of your own planned or preferred social clock. What factors do you think will make it more or less likely that you will be able to follow the timeline?
