The perceived legitimacy of statutory rape laws: the effects of victim age,perpetrator age,and age span

Statutory rape laws are intended to protect minors below the age of consent from engaging in behavior that, although not forceful, may be harmful. Two studies explored how individual judgments of adolescent sexual behavior and statutory rape are affected by victim age, perpetrator age, and the age span between partners. Across studies, respondents were significantly more critical of scenarios depicting younger victims, older perpetrators, and larger age spans between the two. These findings, using indirect measures, suggest that college students believe 16 is an appropriate age of consent and that sexual acts between adolescents who are within 2 years of age should not be criminalized.     

Personality,age, and fluid intelligence

A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers‐Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation‐Behavior (FIRO‐B), and the California Psychological Inventory‐434 (CPI‐434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO‐B), intellectual efficiency (CPI‐434), achievement via independence (CPI‐434), and negatively correlated with sensing (MBTI), internality (CPI‐434) and norm‐favouring (CPI‐434), supporting the majority of the hypotheses. Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered.     

Regret appraisals, age, and subjective well-being

This study examined whether regrets are associated with age and subjective well-being in a sample of 176 participants ranging in age 19 to 82 years. Participants were asked to name unattained goals or events which they currently regret, and appraise these along a number of dimensions such as changeableness and consequences. The results showed that those who appraised their regret-related goals or events as having an impact on their present lives, reported a lower level of life satisfaction and more physical symptoms than those who appraised their regrets as having less consequence. There were also age differences in the regret appraisals. The older adults evaluated their regret-related goals or events as being less likely to change than did the younger adults.     

Visual masking,mental age,and retardation

Performance of retarded subjects under both forward and backward masking was less accurate than either an equivalent chronological age or equivalent mental age group of normals. It was suggested that the iconic memory impairment of retarded subjects in attributable in part to mental retardation and not simply to low mental age.     

Pleasurable emotions,age, and life satisfaction

The self-reported experiences of five distinct pleasurable emotions (tranquility, contentment, interest, cheerfulness, and vigor), as well as the relation between pleasurable emotions and life satisfaction, were examined in a sample of 173 pairs of younger and older adults (mean ages of 18.9 and 74.4?years, respectively). Older individuals reported significantly higher levels of cheerfulness and contentment than did younger individuals. The relation between pleasurable emotions and life satisfaction was significantly moderated by age. Specifically, life satisfaction was more strongly associated with tranquility among older individuals than among younger individuals (with a similar, albeit weaker, trend for contentment).     

How type of excuse defense, mock juror age, and defendant age affect mock jurors' decisions

The authors investigated the effects of mock juror age (younger vs. older), defendant age (22 vs. 65), and type of excuse defense used by defendants (a highly self-inflicted condition, Cocaine Dependency Disorder, vs. a less self-inflicted condition, Posttraumatic Stress Disorder) on mock juror decisions. Ninety-six younger and 96 older adults read a scenario and answered a questionnaire. Results indicated that the defendant using the highly self-inflicted excuse was more likely to receive a guilty verdict and a longer sentence than was the defendant using the less self-inflicted excuse. Older jurors were more certain of their verdicts and saw the defendant as more responsible for his condition than did younger jurors. Defendant age did not affect juror decisions. In addition, excuse type and juror age affected the jurors' perceptions of the victim's responsibility for the attack. The authors discuss the potential influence of juror age on perceptions of defendant responsibility.     

Personality trait development from age 12 to age 18: longitudinal,cross-sectional,and cross-cultural analyses

Three studies were conducted to assess mean level changes in personality traits during adolescence. Versions of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992a) were used to assess the 5 major personality factors. A 4-year longitudinal study of intellectually gifted students (N = 230) was supplemented by cross-sectional studies of nonselected American (N = 1,959) and Flemish (N = 789) adolescents. Personality factors were reasonably invariant across ages, although rank-order stability of individual differences was low. Neuroticism appeared to increase in girls, and Openness to Experience increased in both boys and girls; mean levels of Extraversion, Agreeableness, and Conscientiousness were stable. Results extend knowledge of the developmental curve of personality traits backward from adulthood and help bridge the gap with child temperament studies.     

Visual short-term memory, response delay, and age

Recall and recognition memory performance of 12 young (M = 19 yr.) and 12 older (M = 72 yr.) females was studied in relation to response delay (5, 25, and 125 sec.) and stimulus complexity (6.1 and 13.7 bits of information). The subjects were matched on verbal IQ, visual acuity, and educational levels. Stimuli were abstract, black and white, 4 X 4 square matrices. Age-related decrements in memory performance were associated with stimulus complexity but not with response delay. Older subjects also reported experiencing encoding difficulties during the registration phase. The results were discussed with reference to the locus of age-related decrements in visual short-term memory.     

Emotion, physiology, and expression in old age

Emotion-specific autonomic nervous system (ANS) activity was studied in 20 elderly people (age 71-83 years, M = 77) who followed muscle-by-muscle instructions for constructing facial prototypes of emotional expressions and relived past emotional experiences. Results indicated that (a) patterns of emotion-specific ANS activity produced by these tasks closely resembled those found in other studies with younger Ss, (b) the magnitude of change in ANS measures was smaller in older than in younger Ss, (c) patterns of emotion-specific ANS activity showed generality across the 2 modes of elicitation, (d) emotion self-reports and spontaneous production of emotional facial expressions that occurred during relived emotional memories were comparable with those found in younger Ss, (e) elderly men and women did not differ in emotional physiology or facial expression, and (f) elderly women reported experiencing more intense emotions when reliving emotional memories than did elderly men.     

Structural brain variation,age, and response time

Response time (RT) generally slows with aging, but the contribution of structural brain changes to this slowing is unknown. We used voxel-based morphometry (VBM) to determine gray matter (GM) and white matter (WM) brain volumes in 9 middle-aged adults (38–58 years old) and 9 seniors (66–82 years old). We correlated brain volumes with RT assessed in both a simple visual stimulus-response task and a visual continuous recognition memory task. No GM correlations with simple RT were significant; there was one WM correlation in the right fusiform gyrus. In the memory task, faster RT was correlated (p<.05, corrected) with less GM in the globus pallidus, the parahippocampus, and the thalamus for both groups. Several Brodmann areas (BA) differed between the groups such that in each area, less GM was correlated with slower RTs in the middle-aged group but with faster RTs in the senior group (BAs 19, 37, 46, 9, 8, 6, 13, 10, 41, and 7). The results suggest that individual differences in specific brain structure volumes should be considered as potential moderating factors in cognitive brain imaging studies.     

Type A behavior, age, and psychological well-being

We investigated psychological well-being among Type A and B individuals across the age span. We hypothesized that the hard-driving, achievement-oriented lifestyle exhibited by Type As would be adaptive in younger age groups, but would lead to lower well-being in later life because of increased limitations on the range and level of one's activities. By contrast, the more relaxed, easygoing style of the Type B matches better the slower pace of old age, but is not as conducive to success in younger age groups. Thus we expected older Type Bs more than younger Type Bs to exhibit greater well-being. Results confirmed these hypotheses, but indicated that psychological differences may be mediated in part by differences in physical well-being. Furthermore, experience with life events, and the structure and function of social networks, may contribute to the differences in well-being.
