Reduced specificity of emotional autobiographical memories following self-regulation depletion

The present study used a Color Stroop task, involving naming the ink colors of incongruous color words, to deplete self-regulation resources prior to retrieving a series of autobiographical memories to emotional and neutral cue words--the Autobiographical Memory Test (AMT). Control participants either read color words written in black ink or performed no task prior to the AMT. Difficulty accessing specific memories on the AMT has been shown to index key aspects of the onset and maintenance of depression and other emotional disorders. Our hypothesis that depleted participants would retrieve fewer specific memories to cues on the AMT relative to controls was supported, even when levels of depressed and anxious mood, an index of clinical depression, posttraumatic stress, and verbal intelligence were covaried. The results indicate that self-regulation depletion via a neutral, unrelated task can impact on emotion-related autobiographical memory processes that have been shown to be dysfunctional in emotionally disordered populations.     

Levels of specificity of autobiographical memories and of biographical memories of the deceased in bereaved individuals with and without complicated grief

Traumatized individuals experiencing posttraumatic stress have difficulty retrieving specific autobiographical memories to cue words on the Autobiographical Memory Test (AMT; J. M. G. Williams & K. Broadbent, 1986). This may represent a generalized, functional avoidance of the personal past. However, such individuals also often report specific intrusive memories of their trauma in the day-to-day. This raises the possibility that memories tied to the source of the person's distress are immune to this putative avoidance process. This was investigated in bereaved individuals with complicated grief (CG) who reported intrusive, specific memories from the life of their deceased loved one, and matched bereaved controls without CG. Participants performed the AMT and two Biographical Memory Tests (BMTs), cueing memories from the life of the deceased (BMT-Deceased) and from a living significant other (BMT-Living). To negative word cues, the CG group showed reduced specificity for the AMT and BMT-Living, relative to controls, but this effect was reversed on the BMT-Deceased. These data support the proposal that memories tied to the source of an individual's distress are immune to the processes that underlie the standard reduced specificity effect.     

Medicare's search for effective obesity treatments: diets are not the answer

The prevalence of obesity and its associated health problems have increased sharply in the past 2 decades. New revisions to Medicare policy will allow funding for obesity treatments of proven efficacy. The authors review studies of the long-term outcomes of calorie-restricting diets to assess whether dieting is an effective treatment for obesity. These studies show that one third to two thirds of dieters regain more weight than they lost on their diets, and these studies likely underestimate the extent to which dieting is counterproductive because of several methodological problems, all of which bias the studies toward showing successful weight loss maintenance. In addition, the studies do not provide consistent evidence that dieting results in significant health improvements, regardless of weight change. In sum, there is little support for the notion that diets lead to lasting weight loss or health benefits.     

Reduced specificity of autobiographical memories following a negative mood induction

Reduced autobiographical memory specificity (AMS) to emotional and neutral cue words appears to be a stable cognitive marker of clinical depression. For example, reduced AMS is present in remitted/recovered depressed patients and shows no reliable relationship with current levels of depressed mood in correlational studies. The present study examined whether reduced AMS could be induced in healthy volunteers with no history of depression, using a negative mood manipulation and whether levels of AMS and induced mood were positively correlated. Results showed a reduction in AMS following negative mood induction, compared to a neutral induction, whereas positive mood induction had no effects on AMS. Furthermore, lower happiness following the induction phase correlated positively with reduced AMS, and the extent of happiness reduction from pre- to post-induction correlated positively with reduction in AMS. These results suggest that AMS is, at least in part, a function of current emotion state. The implications for the literature on AMS as a stable marker of clinical depression are discussed.     

Performance feedback,self-esteem,and cardiovascular adaptation to recurring stressors

Background and Objectives: This study sought to examine the effects of performance feedback and individual differences in self-esteem on cardiovascular habituation to repeat stress exposure.

Methods: Sixty-six university students (n?=?39 female) completed a self-esteem measure and completed a cardiovascular stress-testing protocol involving repeated exposure to a mental arithmetic task. Cardiovascular functioning was sampled across four phases: resting baseline, initial stress exposure, a recovery period, and repeated stress exposure. Participants were randomly assigned to receive fictional positive feedback, negative feedback, or no feedback following the recovery period.

Results: Negative feedback was associated with a sensitized blood pressure response to a second exposure of the stress task. Positive feedback was associated with decreased cardiovascular and psychological responses to a second exposure. Self-esteem was also found to predict reactivity and this interacted with the type of feedback received.

Conclusions: These findings suggest that negative performance feedback sensitizes cardiovascular reactivity to stress, whereas positive performance feedback increases both cardiovascular and psychological habituation to repeat exposure to stressors. Furthermore, an individual’s self-esteem also appears to influence this process.     

Genetic Counseling Outcomes: Perceived Risk and Distress After Counseling for Hereditary Colorectal Cancer

Genetic counseling may turn risk information into cancer prevention behavior by modifying health beliefs and cancer-related distress. We assessed the effect of genetic counseling on these factors in 101 adult first-degree-relatives of colorectal cancer patients from families with known or suspected hereditary nonpolyposis colorectal cancer. Before counseling and once afterward, subjects completed self-report measures of perceived lifetime risk and cancer-distress. Most persons overestimated their cancer risk, and higher perceived risk was associated with believing that colorectal cancer cannot be prevented. Individual perceived risk changed after counseling, although mean perceived risk was unchanged. After adjusting for baseline risk, older persons and those with higher estimated objective cancer risk had larger postcounseling decreases. Distress after counseling was positively correlated with baseline distress and anxiety symptoms, and inversely correlated with tolerance for ambiguity. The findings suggest counseling interventions that should increase the likelihood of screening and offer hypotheses for future research.     

The Educational Psychology of Self-Regulation: A Conceptual and Critical Analysis

The multiplicity of definitions and conceptions of self-regulation that typifies contemporary research on self-regulation in psychology and educational psychology is examined. This examination is followed by critical analyses of theory and research in educational psychology that reveal not only conceptual confusions, but misunderstandings of conceptual versus empirical issues, individualistic biases to the detriment of an adequate consideration of social and cultural contexts, and a tendency to reify psychological states and processes as ontologically foundational to self-regulation. The essay concludes with a consideration of educational research and intervention in the area of students’ self-regulated learning in terms of the scientific and professional interests of psychologists and educators, and the disguised manipulation of student self-surveillance in the service of the institutional mandates of schools.
