This article evaluates theories of the origins of sex differences in human behavior. It reviews the cross-cultural evidence on the behavior of women and men in nonindustrial societies, especially the activities that contribute to the sex-typed division of labor and patriarchy. To explain the cross-cultural findings, the authors consider social constructionism, evolutionary psychology, and their own biosocial theory. Supporting the biosocial analysis, sex differences derive from the interaction between the physical specialization of the sexes, especially female reproductive capacity, and the economic and social structural aspects of societies. This biosocial approach treats the psychological attributes of women and men as emergent given the evolved characteristics of the sexes, their developmental experiences, and their situated activity in society. 相似文献

Assessing future possible selves by gender and socioeconomic status using the anticipated life history measure 总被引:2,自引:0,他引:2
This is a report from the first phase of a longitudinal study of the ways young adults imagine their future lives. The future possible selves of 223 18- and 19-year-old adults were examined using the Anticipated Life History measure (ALH), a psychological instrument prompting participants to describe their future life course from their 21st birthday until their death. When the ALH narratives were coded for presence/absence of life events, female participants were more likely to predict career choice, marriage, children, divorce, and death of spouse than their male counterparts; when coded for psychological qualities, female participants demonstrated greater psychological complexity and awareness of future life role choices and conflicts. Participants with lower SES wrote ALH narratives with fewer altruistic acts, less awareness of life role complexity, and fewer anticipated conflicts and their resolutions than those with higher SES. 相似文献

Childhood and adolescent onset conduct disorder: a test of the developmental taxonomy 总被引:1,自引:0,他引:1
Hypotheses generated by a developmental taxonomy that distinguishes between childhood and adolescent onset conduct disorders were tested. Hypotheses predicted that (1) individual and familial factors would be more strongly related to childhood onset conduct disorder, whereas ethnic minority status and exposure to deviant peers would be more strongly related to adolescent onset conduct disorder and (2) individuals with childhood onset disorder would be more likely to commit violent and victim oriented offenses than individuals with adolescent onset conduct disorder. The first hypothesis was strongly supported and the second hypothesis was partially supported. Implications for early identification of youth at risk for chronic offending are discussed. 相似文献

Young adults rated an old female witness (82 years) to be less competent but more honest than a young female witness (28 years). The effect of age stereotyping on believability was assessed indirectly by using a variant of Loftus' misinformation paradigm. Regression analysis showed that the more competent a witness was perceived as being, the more influential was the misinformation she provided. This was true, however, only when the witness was young because the relatively lower competence of the old witness was associated with nonsignificant misinformation effects. These data suggest that negative beliefs associating incompetence with old age may compromise the believability of older eyewitnesses. 相似文献

Larvae of the hawkmoth, Manduca sexta, exhibit a defensive proleg withdrawal reflex in which deflection of mechanosensory hairs on the proleg tip (the planta) evokes retraction of the proleg. A previous behavioral study showed that this reflex habituates in response to repeated planta hair deflection and exhibits several other defining features of habituation. In a semi-intact preparation consisting of a proleg and its associated segmental ganglion, repeated deflection of a planta hair or electrical stimulation of its sensory neuron causes a neural correlate of habituation, manifested as a decrease in the number of action potentials evoked in the proleg motor nerve. Monosynaptic connections from planta hair sensory neurons to the principal planta retractor motoneuron exhibit several forms of activity-dependent plasticity. In the present study we recorded intracellularly from this motoneuron during repetitive electrical stimulation of a planta hair sensory neuron. The number of action potentials evoked in the motoneuron decreased significantly, representing a neural correlate of habituation. The motoneuron's resting membrane potential, input resistance. and spike threshold measured before and after repetitive stimulation did not differ between the stimulated group and a control group. Furthermore, the amplitude of the monosynaptic excitatory postsynaptic potential, as well as the magnitude of paired-pulse facilitation, evoked in the motoneuron by the sensory neuron did not change after repetitive stimulation. These results suggest that depression at the sensorimotor synapse does not contribute to reflex habituation. Rather, other mechanisms in the ganglion of the stimulated segment, such as changes in polysynaptic reflex pathways, appear to be responsible. 相似文献

This study examined the relationship between personality traits, COVID-specific beliefs and behaviors, and well-being during the COVID-19 pandemic. In July 2020, at the onset of a second major lockdown, Australian adults (n = 1453) completed measures of Big Five personality, COVID beliefs and behaviors (i.e., belief in a rapid recovery, perceived risk, compliance, change in exercise, and change in interpersonal conflict), subjective well-being and COVID-specific well-being. Personality correlates of COVID-specific well-being differed from those with general life satisfaction. The benefits of conscientiousness were elevated whereas the benefits of extraversion and agreeableness were reduced. Neuroticism was related to greater perceived risk from the pandemic, elevated interpersonal conflict during the pandemic, and more pessimistic views about the rate at which society would recover from the pandemic. In contrast, conscientiousness was notably related to greater compliance with directions from public health authorities. While regression models showed that general well-being was largely explained by personality, COVID factors provided incremental prediction, and this was greatest when predicting COVID-specific well-being and lowest for global evaluations of life satisfaction. The observed prediction by beliefs and behaviors on well-being beyond personality, provides potential opportunities for targeted interventions to support the management of future novel stressors. 相似文献

The 1993 Biobehavioral Family model (BBFM) posits that family relational patterns and biobehavioral reactivity interact so as to influence the physical and psychological health of the children. The revised 1999 BBFM incorporates parent-child attachment as a pivotal construct. The current study tests the 1999 BBFM by predicting, in asthmatic children, that child perception of parental relationship quality, triangulation of child in marital conflict, and parent-child security of relatedness will be associated with hopelessness and vagal activation (one mechanism of airway compromise in asthma). In this study, 22 children with asthma (11 males/11 females, aged 8 to 16), watched, alone, an emotionally challenging movie, then engaged in family discussion tasks (problem solving, loss, conflict, cohesion) and completed the Children's Perception of Interparental Scale, the Relatedness Questionnaire, The Multidimensional Scale of Anxiety in Children, and the Hopelessness Scale for Children. Heart rate variability, measured at baseline and throughout the movie and family tasks, was used to compute respiratory sinus arrhythmia (RSA)--an inferential measure of vagal activation. The child's perception of parental conflict showed trends of association with triangulation and insecure father-child relatedness. Triangulation and hopelessness also were associated with insecure father-child relatedness, all of which were associated with vagal activation. Insecure mother-child relatedness was correlated only with hopelessness. Anxiety was not related to any variables. These findings lend support to the 1999 BBFM, and suggest a key role for parent-child attachment. 相似文献

Using a cognitive architecture to examine what develops 总被引:1,自引:0,他引:1
Different theories of development propose alternative mechanisms by which development occurs. Cognitive architectures can be used to examine the influence of each proposed mechanism of development while keeping all other mechanisms constant. An ACT-R computational model that matched adult behavior in solving a 21-block pyramid puzzle was created. The model was modified in three ways that corresponded to mechanisms of development proposed by developmental theories. The results showed that all the modifications (two of capacity and one of strategy choice) could approximate the behavior of 7-year-old children on the task. The strategy-choice modification provided the closest match on the two central measures of task behavior (time taken per layer, r = .99, and construction attempts per layer, r = .73). Modifying cognitive architectures is a fruitful way to compare and test potential developmental mechanisms, and can therefore help in specifying "what develops." 相似文献
