The present study was designed to evaluate the extent to which free recall performance is influenced by competing demands on physiological resources dependent on blood‐oxygen levels. Fifty‐six healthy young adults (mean age=20 years) were allocated to groups (n1–4=14) according to their level of exercise (more than 6 h aerobic exercise per wk, or sedentary 1
  • 1 Here sedentary refers to individuals with no regular exercise routines
  • .) and smoking (more than 10 cigarettes per day, or none) behaviour. Participants performed two free recall tasks, one under normal physically inactive conditions and the other immediately following strenuous physical exertion (a step‐up test for 2 min). We predicted that recall would suffer following strenuous physical activity among smoking aerobic exercisers. We reasoned this would be due to the oxygen‐carrying capacity of the blood being compromised in this group by higher levels of smoking‐related carbon monoxide in the blood stream. The results supported this prediction. We interpret our findings according to a resource model of cognitive function, mediated by physiological mechanisms.

    A total of 480 patients were treated in a large, multicenter randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behavior therapy (MACT) versus treatment as usual (TAU) for recurrent deliberate self-harm. Each patient was randomized after a self-harm episode assessed at an accident and emergency center and followed up over 1 year. The main hypothesis tested was that those allocated to MACT would have a lower proportion of self-harm episodes in the succeeding year. A total of 60% of those allocated to MACT had face-to-face treatment and 430 (90%) of all patients had self-harm data recorded after 1 year. Although the results showed no significant difference between those repeating self-harm in the MACT group (39%) compared with the TAU group (46%) (P = 0.20), the treatment was cost effective (10% cheaper than TAU) and the frequency of self-harm episodes was fewer (50%) in the MACT group. A total of nine of 10 patients had some personality disturbance (42% of these with disorder), and for those where information on parasuicide events was collected, the proportion having a repeat episode ranged from 33% to 63% for different personality disorders. Those with BPD were most likely to repeat episodes quickly (mean 89 days for 25% to repeat) with dissocial personality disorder (equivalent mean 384 days) the slowest to repeat. Total costs were significantly greater in those with personality disorder and were reduced in those allocated to MACT; this saving was reversed in those with borderline disorder. On average, MACT appeared to increase the cost of those patients with BPD (BPD) and reduce the cost of those with other personality disorders. It is concluded that MACT has value in preventing self-harm cost effectively but this appears to be confined mainly to those who do not have BPD.  相似文献

    This study sought to examine one aspect ofstereotyping in television advertising, specifically,the use of animated spokes-characters as productrepresentatives and whether spokes-characters contribute to gender-stereotyped portrayals. Undergraduatestudents — of a variety of races and an almostequal number of men and women — identifiedmemorable spokes-characters, presumed genders, notedgender-distinguishing characteristics, and viewed programmingfeaturing commercials with spokes-characters. Hypotheseswere confirmed that participants will recall more maleanimated characters than female and that most of the spokes-characters in television advertising aremale. Using male spokes-characters reinforces thestereotypical notion that males are more important thanfemales. Such effects may be greater than those associated with other aspects of advertisinglargely because of the memorability and popularity ofanimated spokes-characters.  相似文献

    Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented.  相似文献

    This meta-analysis addresses the association between perceived employability (PE) and employee strain (k = 34). Consistent with expectations, PE was negatively related to strain (ρ = −.12, 95% CI = −.16 to −.08). Moderator analysis showed that this relationship was stronger post-2008 (ρ = −.20, 84% CI = −.23 to −.17) versus pre-2008 (ρ = −.06, 84% CI = −.08 to −.05) and in high (ρ = −.17, 84% CI = −.21 to −.14) versus low (ρ = −.07, 84% CI = −.09 to −.06) uncertainty avoidant cultures. Our results suggest that career competency development interventions can be effective for reducing employee strain and that national uncertainty avoidance need be incorporated into models of boundaryless careers, especially as it relates to employee health and well-being.  相似文献

    Premature birth has a well-documented impact on infants, mothers and their dyadic interactions. First time motherhood in the context of low risk premature birth—relatively unexplored in the literature—is a specific experience that sits at the nexus of premature infancy, motherhood and the processes that underpin dyadic connection. This qualitative study analyzed semistructured interviews with first time mothers of low risk premature babies. Findings were generated in response to research questions concerning mothers’ meaning-making, bonding and identity. Findings demonstrated that maternal meaning-making emerged from a dyadic framework. When mothers or their infants were considered outside of a dyadic context, surplus suffering inadvertently occurred. Findings have important implications for infant mental health practice in medical settings, for postnatal support in the aftermath of premature birth, and for understanding the meaning of risk.  相似文献

    Research into the development of Theory of Mind (ToM) has shown how children from a very early age infer other people's goals. However, human behaviour is sometimes driven not by plans to achieve goals, but by habits, which are formed over long periods of reinforcement. Habitual and goal‐directed behaviours are often aligned with one another but can diverge when the optimal behavioural policy changes without being directly reinforced (thus specifically hobbling the habitual learning strategy). Unlike the flexibility of goal‐directed behaviour, rigid habits can cause agents to persist in behaviour that is no longer adaptive. In the current study, all children predict agents will tend to behave consistently with their goals, but between the ages of 5 and 10, children showed an increasing understanding of how habits can cause agents to persistently take suboptimal actions. These findings stand out from the typical way the development of social reasoning is examined, which instead focuses on children's increasing appreciation of how others' beliefs or expectations affect how they will act in service of their goals. The current findings show that children also learn that under certain circumstances, people's actions are suboptimal despite potentially ‘knowing better.’  相似文献

    An attempt was made to identify obsessive-compulsive disorder (OCD) subgroups based on differences in OCD related beliefs. OCD patients (N=367) were assessed with the Obsessional-Beliefs Questionnaire prior to treatment. Individuals' scores on measures of inflated personal responsibility and the tendency to overestimate threat, perfectionism and intolerance of uncertainty, and over-importance and over-control of thoughts were subjected to cluster analysis. Support for both a simple and complex subgroup model was found (2-subgroup and 5-subgroup taxonomies). A low-beliefs subgroup was identified in both taxonomies. The low-beliefs subgroups reported scores on belief measures equivalent to scores reported for non-OCD comparison groups in earlier studies. Additional analyses were conducted to determine relations between belief-based and symptom subgroups. Significant relationships were found (e.g., Symmetry symptom subgroup membership was associated with membership in the Perfectionism/Certainty beliefs subgroup), although the shared variance was modest. Implications for understanding OCD heterogeneity and for cognitive theory are discussed.  相似文献

    A longitudinal study examined relations between 2 approaches to identity development: the identity status model and the narrative life story model. Turning point narratives were collected from emerging adults at age 23 years. Identity statuses were collected at several points across adolescence and emerging adulthood, as were measures of generativity and optimism. Narratives were coded for the sophistication of meaning-making reported, the event type in the narrative, and the emotional tone of the narrative. Meaning-making was defined as connecting the turning point to some aspect of or understanding of oneself. Results showed that less sophisticated meaning was associated particularly with the less advanced diffusion and foreclosure statuses, and that more sophisticated meaning was associated with an overall identity maturity index. Meaning was also positively associated with generativity and optimism at age 23, with stories focused on mortality experiences, and with a redemptive story sequence. Meaning was negatively associated with achievement stories. Results are discussed in terms of the similarities and differences in the 2 approaches to identity development and the elaboration of meaning-making as an important component of narrative identity.  相似文献
