Sex differences in duration judgments: A meta-analytic review

We quantitatively reviewed human sex differences in the magnitude and variability of duration judgments. Data from 4,794 females and 4,688 males yielded 87 effect size estimates of magnitude and 28 of variability. The overall sex difference in duration judgment magnitude was small but statistically significant. It was moderated by whether study participants knew in advance (prospective paradigm) or only later (retrospective paradigm) that they would be required to judge duration. Although prospective judgments showed no overall sex effect, some levels of moderator variables showed a small but statistically significant effect. Retrospective judgments showed a larger subjective-to-objective duration ratio for females than for males, and several variables moderated this effect. Females' judgments also showed more intersubject variability than did males' judgments. Relative to males, females sustain attention to time more in the prospective paradigm and have better episodic memory in the retrospective paradigm.     

On the number of significant findings to be expected by chance

When multiple significance tests are computed, a certain number of significant findings will emerge simply because of chance fluctuations. In the present paper, some factors affecting the number of nominally significant results are elaborated and a general method is suggested which permits unbiased inference as to the significance of a set of findings,as a set. The method advocated employs a high speed computer to generate empirically a sampling distribution tailormade to a particular data matrix. The method is illustrated in the case of dichotomous response to inventory items, where it is found that the statistical model still often used as a basis for estimation is overly conservative. Some problems in the application of the method are discussed.This investigation, part of a larger research project, was supported primarily by research grant M-1078 from the National Institute of Mental Health of the United States Public Health Service. Gratitude is also extended to the National Science Foundation for making available research time on the IBM Model 701 computer. The present paper has benefited greatly from the comments on an earlier version offered by John Tukey and an editor ofPsychometrika.     

Interfering with memory for faces: The cost of doing two things at once

We inferred the processes critical for episodic retrieval of faces by measuring susceptibility to memory interference from different distracting tasks. Experiment 1 examined recognition of studied faces under full attention (FA) or each of two divided attention (DA) conditions requiring concurrent decisions to auditorily presented letters. Memory was disrupted in both DA relative to FA conditions, a result contrary to a material-specific account of interference effects. Experiment 2 investigated whether the magnitude of interference depended on competition between concurrent tasks for common processing resources. Studied faces were presented either upright (configurally processed) or inverted (featurally processed). Recognition was completed under FA, or DA with one of two face-based distracting tasks requiring either featural or configural processing. We found an interaction: memory for upright faces was lower under DA when the distracting task required configural than featural processing, while the reverse was true for memory of inverted faces. Across experiments, the magnitude of memory interference was similar (a 19% or 20% decline from FA) regardless of whether the materials in the distracting task overlapped with the to-be-remembered information. Importantly, interference was significantly larger (42%) when the processing demands of the distracting and target retrieval task overlapped, suggesting a processing-specific account of memory interference.     

Intent to remember briefly presented human faces and other pictorial stimuli enhances recognition memory

Since the early days of psychology, researchers have investigated whether or not intending to remember information affects subsequent memory performance. The literature contains methodological issues and empirical contradictions, with ambiguous effects. In five experiments, a total of 576 participants viewed a rapid series of pictorial stimuli under either incidental- or intentional-memory conditions. Although the methodology was stringent, intent to remember consistently enhanced recognition memory. Recognition was enhanced even when participants viewed a picture of a human face, of an ape face, or of a bird for as little as 0.5-1.0 sec, with no interstimulus interval between it and the next picture. Rehearsal, depth of processing, and attentional allocation are discussed to explain how people might intentionally encode pictorial information to enhance their subsequent recognition memory performance.     

How do women experience myocardial infarction? A qualitative exploration of illness perceptions, adjustment and coping

While UK Department of Health policy recognizes the importance of secondary prevention and rehabilitation following a cardiac event, there still appears a dearth of research addressing women's needs. This study aimed to explore adjustment in terms of women's perception of their cardiac event, impact on relationships and coping strategies employed. Five women suffering first time MI were interviewed, using a semi-structured format and were telephoned 2 months later. Data were analysed using Interpretative Phenomenological Analysis. Perceptions included: Making Sense of the Event, Cognitive and Emotional Responses and Self-beliefs. Relationships issues were: Others' Reactions and Change in Relationships and Roles. Cognitive and Behavioural strategies and Support from others (including cardiac rehabilitation) formed coping strategies. For most participants, the event was unexpected evoking uncertainty and later, emotions extending beyond the more widely accepted depression and anxiety. Women tended to minimize severity of symptoms and impact of event (perhaps as a way of coping and protecting others), displaying a strong sense of optimism and hope that life would soon return to "normal". However, it appeared this was difficult to maintain and the experience seemed to challenge relationships and roles. The findings suggest recommendations for further research with possible implications for clinical practice.
