Psychological closure as a memory phenomenon

A theory is proposed that life events are remembered with a satisfying sense of closure when there is decreased emotional detail in the constructed autobiographical memory representation. The first three studies show that, although properties of the experienced event (such as valence and recency) accounted for some variance in participants' sense of closure, the amount of emotional detail in the memory was also a significant predictor. The third study shows that emotion-focused biased retelling of the experience increased emotional detail and decreased the sense of closure participants reported. Related approaches and implications for psychological adjustment are discussed.     

Guiding the creation of knowledge and understanding in a virtual learning environment.

This article reports findings from an in-depth case study investigating processes of teaching and learning within one tutorial group studying an e-learning course presented as part of the Open University's MA in Open and Distance Education. Drawing on contemporary sociocultural theory and research, the instructional techniques used by the tutor-moderator to guide the creation of "common knowledge" and the construction of understanding are explored. The significance of tutor contributions for fostering a supportive culture of enquiry is also discussed.     

ERP study of pre-attentive auditory processing in treatment-refractory schizophrenia

Event-related potential (ERP) studies have demonstrated impaired auditory sensory processing in patients with schizophrenia, as reflected in abnormal mismatch negativity (MMN). We sought to extend this finding by evaluating MMN in 13 treatment-refractory patients with schizophrenia, and 14 age- and gender-matched healthy controls. Subjects responded to infrequent visual stimulation while ignoring binaurally presented auditory tones. The amplitude and topographical pattern of the MMN were analyzed. The control group presented the expected reduction in the amplitude of the MMN from frontal to central and parietal locations. In comparison, the MMN amplitude was not reduced in the treatment-refractory patients, and was largest at the central-posterior electrode location. In addition, patients displayed larger negativities at left frontal, and left- and right-temporal electrode locations than the control subjects. These findings are consistent with pre-attentive abnormalities in treatment-refractory patients with schizophrenia.     

Hemispheric asymmetries for selective attention apparent only with increased task demands in healthy participants

This study examined the possibility that lack of behavioral evidence indicating hemispheric specialization for selective attention in healthy individuals is due to the use of tasks that are not sufficiently demanding to require selective attention. In a group of 43 participants (ages 17-23), we compared selective attention on a cued-response time task when the target was presented alone and when a distractor was simultaneously presented. The costs of invalid cueing were minimal when the right hemisphere (RH) processed the target relative to when the left hemisphere (LH) processed the target, but only for the high load condition. These results are interpreted as RH specialization in light of evidence suggesting that the RH can direct attention to a larger portion of the visual field.     

Mere presence is not enough: Responsive support in a virtual world

When individuals are faced with novel or threatening situations, the presence of a trusted companion should reduce anxiety and promote feelings of security. Attachment theory assumes, however, that mere presence is not sufficient for establishing security; an attachment figure must also be attentive and emotionally responsive. To test this idea, participants came to the lab with their romantic partner and completed a threatening cliff-walking task in a digital immersive virtual environment. The presence and nonverbal support behavior (attentive vs. inattentive) of their partner was experimentally manipulated. Results indicated that participants in the attentive-partner condition experienced the task as less stressful than those who were alone; they also reported feeling more secure during the task and were less vigilant of their partner's behavior compared to those in the inattentive-partner condition. Those in the inattentive-partner condition felt less cared for and kept greater physical distance from their partner on a subsequent task. These findings suggest that human beings are predisposed to monitor their social environment for signs of responsiveness, and that perceived responsiveness, not mere presence, is the key modulator of emotional security.     

License to sin: Self‐licensing as a mechanism underlying hedonic consumption

Hedonic overconsumption is often considered to be caused by impulsive factors. The current paper investigates whether self‐licensing, relying on reasons to justify subsequent gratification, can also be included as a significant contributor to hedonic consumption. Two studies were conducted to investigate whether self‐licensing can account for an increase in hedonic consumption while ruling out impulsive factors such as resource depletion, negative affect, and visceral state as alternative explanations. A pilot study indicated that perceiving oneself as having invested greater effort and thus having a self‐licensing cue did not lead to a decline in self‐control capacity compared with not having a self‐licensing cue. The main study employed the same procedure and established that having a licensing cue did lead to increased snack intake while controlling for impulsive factors. Together, these studies support the notion that self‐licensing is a separate mechanism leading to hedonic gratification independent of impulsive factors. Copyright © 2011 John Wiley & Sons, Ltd.
