A strategy disruption component to retrieval-induced forgetting

Retrieval-induced forgetting refers to a paradoxical occurrence wherein the act of remembering some material disrupts the retrieval of other, related material (see, e.g., M. C. Anderson, R. A. Bjork, & E. L. Bjork, 1994). This effect is generally accounted for in terms of inhibitory processes. Across three experiments, we test the inhibitory account of retrieval-induced forgetting, as well as whether there may be a strategy disruption component to the effect. In our first two experiments, we manipulate which items individuals are cued to recall during retrieval practice and demonstrate that retrieval-induced forgetting can be neutralized when those items do not interfere with the individual's retrieval strategy. In the third experiment, we confirm this finding with a different set of stimuli. These results are inconsistent with a purely inhibitory account of retrieval-induced forgetting, and we discuss implications for inhibition theory and strategy disruption in light of these and other findings.     

The Relationship Between Parent and Child Dysfunctional Beliefs About Sleep and Child Sleep

Cognitive theories emphasise the role of dysfunctional beliefs about sleep in the development and maintenance of sleep-related problems (SRPs). The present research examines how parents’ dysfunctional beliefs about children’s sleep and child dysfunctional beliefs about sleep are related to each other and to children’s subjective and objective sleep. Participants were 45 children aged 11–12 years and their parents. Self-report measures of dysfunctional beliefs about sleep and child sleep were completed by children, mothers and fathers. Objective measures of child sleep were taken using actigraphy. The results showed that child dysfunctional beliefs about sleep were correlated with father (r = 0.43, p < 0.05) and mother (r = 0.43, p < 0.05) reported child SRPs, and with Sleep Onset Latency (r = 0.34, p < 0.05). Maternal dysfunctional beliefs about child sleep were related to child SRPs as reported by mothers (r = 0.44, p < 0.05), and to child dysfunctional beliefs about sleep (r = 0.37, p < 0.05). Some initial evidence was found for a mediation pathway in which child dyfunctional beliefs mediate the relationship between parent dysfunctional beliefs and child sleep. The results support the cognitive model of SRPs and contribute to the literature by providing the first evidence of familial aggregation of dysfunctional beliefs about sleep.     

The sources of visual recency: Movement and language in serial recall

Four experiments examine the importance of movement—the sequential ordering of stimulus features—in producing recency in the ordered serial recall of visual lists. The written recall of handsigns produced more recency when they were seen moving than still (Experiment I). Number lists presented as moving bar figures showed more recency than numbers which were displayed in the normal way with all features displayed simultaneously (Experiment II). The order in which features of abstract shapes are displayed can, itself, determine recency (Experiment III). However, a final experiment showed that still lip pictures of speech sounds generate more recency than letters representing those speech sounds. Therefore movement of stimulus features need not account for the extensive recency advantage in remembering lipread lists. The theoretical implications of these findings are discussed.     

He's gotta have it: shopping dependence and the homosexual male clothing consumer

Shopping is not always ‘fun’ and is not always ‘therapeutic’, yet, the negative aspects and motivations for this behaviour have received little attention. Consumers often may be dependent upon shopping activity to satisfy personal needs, such as emotional repair and self‐image, which are far removed from the acquisition and use of products. Not only may this dependence be dysfunctional in that it signals an individual's inability to control their shopping behaviour but also it may be symptomatic of more serious problems, such as compulsive and even addictive shopping. This paper explores this shopping dependence in the context of fashion clothing consumption. Male consumers are considered, with sexual orientation employed as an indicator of behaviour. Data from a survey of 225 homosexual and 225 heterosexual UK males suggest that homosexual males display clothes shopping dependence, and at a level that is significantly stronger than for heterosexuals. Younger males show a greater tendency to display such behaviour, with dependence declining with age for both groups. Managerial and research implications are considered.

The politics of attention: gaze-cuing effects are moderated by political temperament

Gaze cues lead to reflexive shifts of attention even when those gaze cues do not predict target location. Although this general effect has been repeatedly demonstrated, not all individuals orient to gaze in an identical manner. For example, the magnitude of gaze-cuing effects have been reduced or eliminated in populations such as those scoring high on the Autism-Spectrum Quotient and in males relative to females (since males exhibit more autism-like traits). In the present study, we examined whether gaze cue effects would be moderated by political temperament, given that those on the political right tend to be more supportive of individualism--and less likely to be influenced by others--than those on the left. We found standard gaze-cuing effects across all subjects but systematic differences in these effects by political temperament. Liberals exhibited a very large gaze-cuing effect, whereas conservatives showed no such effect at various stimulus onset asynchronies.     

Quasi-miracles,typicality, and counterfactuals

If one flips an unbiased coin a million times, there are 2^1,000,000 series of possible heads/tails sequences, any one of which might be the sequence that obtains, and each of which is equally likely to obtain. So it seems (1) ‘If I had tossed a fair coin one million times, it might have landed heads every time’ is true. But as several authors have pointed out, (2) ‘If I had tossed a fair coin a million times, it wouldn’t have come up heads every time’ will be counted as true in everyday contexts. And according to David Lewis’ influential semantics for counterfactuals, (1) and (2) are contradictories. We have a puzzle. We must either (A) deny that (2) is true, (B) deny that (1) is true, or (C) deny that (1) and (2) are contradictories, thus rejecting Lewis’ semantics. In this paper I discuss and criticize the proposals of David Lewis and more recently J. Robert G. Williams which solve the puzzle by taking option (B). I argue that we should opt for either (A) or (C).
