Exploring the peak and end rule of past affective episodes within the exercise context

ObjectivesThe global affective evaluation (GAE) of an event influences the decision to repeat that event. Two moments are proposed to predict the GAE: the peak and end affect experienced from the event (Fredrickson, 2000). The purposes of this study were to test this peak and end rule in the context of exercise and examine the relationship between GAE and exercise behaviour.Methods41 inactive women (M = 42.7 years, SD = 10.6 years) completed a graded exercise test to determine ventilatory threshold (VT) and 20 min of treadmill exercise at an intensity either at-VT or 10% above-VT. Feeling Scale (FS) was recorded every 2 min during-exercise and 1, 5, 10 and 15 min post-exercise. GAE was measured 5 min, 15 min, 2 and 7 days post-exercise. Exercise intentions and behaviour were measured 7 days post-exercise. The individual's peak and end FS values were entered together as predictor variables in separate regression analyses with GAE from each time point as the dependent variable.ResultsPeak affect and end affect explained between 39 and 58% of the variance in GAE. Greater variance was predicted 5 and 15 min post-exercise compared with 2 and 7 days post-exercise. The independent contribution of the peak and end variables could not be determined due to multi-collinearity problems. No significant relationships existed between affective memory and intentions or behaviour.ConclusionsThe peak and end rule plays some part in predicting the affective memory of an exercise experience but other variables are likely to play a role.     

Psychological Determinants of Optimism Regarding Consequences of the War

Gazing behavior of 10 three-month-old twin infants (five male and five female) and their mothers during play, bottle feeding, and spoon feeding activities were analyzed. Video-tape equipment was used in the home; data were gathered as naturalistically as possible. Mothers looked at infants for a greater percentage of the total time and for longer durations than infants looked at mothers. A consistency-activation personality theory in which mothers are highly motivated to gaze at infants, but infants seek visual interest by looking away from mother, is suggested to interpret the findings. Both looking and not-looking gazes and mean and median measures of central tendency were shown to be helpful and necessary for the gazing analysis.     

Behaving badly: A perspective on mechanisms of dysfunction in psychopathy

Psychopathy is a personality construct defined by lack of empathy, impulsivity, grandiosity, callous and manipulative interpersonal interactions, and the tendency to engage in socially deviant behavior. Psychopathy has been associated with aggression, recidivism, and other behaviors harmful to others. Individuals high in psychopathy have been thought to be notoriously difficult to treat. Many scholars have suggested that considering mechanisms of dysfunction in psychological difficulties will lead to the development of more effective and efficacious treatments. Fearlessness, lack of empathy, and response modulation difficulties have commonly been discussed as mechanisms of dysfunction in psychopathy. The current review provides a brief overview of examinations of these mechanisms of dysfunction in psychopathy, comments on research methodology, and provides suggestions for remedying potential pitfalls.     

Adult recollections of earliest childhood dreams: A cross-cultural study

In two studies, Caucasian and Asian college students recalled their earliest memory of a dream, and they provided information about behaviours and beliefs associated with dreaming. Consistent with previous research on childhood amnesia, participants rarely recounted dreams that occurred before age 3. In Study 1, the mean age of the earliest dream memory was 14 months earlier for Caucasians than for Asians. In Study 2, more Asians than Caucasians were unable to remember a childhood dream. Dream-related behaviours and beliefs also differed markedly across cultures. Compared to Asians, Caucasians reported talking more frequently with parents about their dreams in childhood, receiving stronger parental encouragement to share dreams, and feeling more comfortable doing so. Caucasians also reported sharing their dreams with others more frequently in adulthood and they assigned greater value to their dreams. Most Caucasians but few Asians consented to the researchers' request to send parents a questionnaire concerning the participant's childhood dreams. The results support the social interaction explanation for autobiographical memory development, in which parent–child conversations about the personal past contribute to memory accessibility.     

Why recall our highs and lows: Relations between memory functions,age, and well-being

This study examined whether positive and negative memories (life story high and low points) were differentially used for reminiscence functions concerning self and social aspects of reminiscing, and relations between function use and well-being in two age groups. Life story high and low points were collected from a sample of emerging (n =56) and older (n =55) adults, as well as a measure of the use of these memories for the self-functions of death preparation, identity, and problem solving, and the social functions of conversation and teach/inform, and a measure of psychological well-being. Memories were also coded for whether or not they contained a redemptive narrative structure (from emotionally negative to emotionally positive). Results showed that the endorsement of reminiscence functions did differ by memory type, with high points more often endorsed for the functions of identity, teach/inform, and conversation than low points. These main effects were qualified by memory type × age interactions. The use of these functions for each kind of memory was also related to well-being, but differentially for older and younger people, and redemptive sequencing was especially important to the well-being of the younger group. Findings are discussed in terms of the importance of different emotional memories for self and well-being at different points in the lifespan.     

Effectiveness of virtual reality distraction during a painful medical procedure in pediatric oncology patients

The effectiveness of virtual reality (VR) as a behavioral intervention designed to decrease distress during port access procedure was examined in 20 7- to 14-year-old pediatric oncology patients. Children were randomized to either engage in an immersive VR environment during the procedure or to a no VR control condition. Children's distress was assessed through subjective self-ratings and objective physiological and behavioral ratings. Narrative accounts of the experience were used as a measure of how well the child coped with the procedure. VR was effective in reducing children's distress on all measures. Implications of these findings for intervention are discussed.     

Computerised Cognitive Behavioural Therapy for Common Mental Health Disorders, What Works, for Whom Under What Circumstances? A Systematic Review and Meta-analysis

This systematic review and meta-analysis evaluates the effectiveness of computerised cognitive behavioural therapy (CCBT) as a low intensity intervention for common mental health disorders (CMHD), and investigates some potential moderators of these effects. A meta-analysis was conducted on 49 randomised controlled trials comparing CCBT to other therapies (n = 24) and waiting list controls (n = 25), across the range of CMHD. Results indicated an overall mean effect size of g = 0.77 (95 % CI 0.59–0.95) in favour of the CCBT trial arms. CCBT was found to be significantly more effective than both waitlist and active control conditions. The mean age of study sample and type of control group both significantly moderated this effect. No further measured variables, including guidance were found to moderate this effect. These findings indicate that CCBT can be an effective low-intensity intervention for CMHD and support the implementation of CCBT within the stepped-care context. Limitations of this review, and implications for theory, research and practice are discussed.
