The academic outcomes of working memory and metacognitive strategy training in children: A double‐blind randomized controlled trial

Working memory training has been shown to improve performance on untrained working memory tasks in typically developing children, at least when compared to non‐adaptive training; however, there is little evidence that it improves academic outcomes. The lack of transfer to academic outcomes may be because children are only learning skills and strategies in a very narrow context, which they are unable to apply to other tasks. Metacognitive strategy interventions, which promote metacognitive awareness and teach children general strategies that can be used on a variety of tasks, may be a crucial missing link in this regard. In this double‐blind randomized controlled trial, 95 typically developing children aged 9–14 years were allocated to three cognitive training programmes that were conducted daily after‐school. One group received Cogmed working memory training, another group received concurrent Cogmed and metacognitive strategy training, and the control group received adaptive visual search training, which better controls for expectancy and motivation than non‐adaptive training. Children were assessed on four working memory tasks, reading comprehension, and mathematical reasoning before, immediately after, and 3 months after training. Working memory training improved working memory and mathematical reasoning relative to the control group. The improvements in working memory were maintained 3 months later, and these were significantly greater for the group that received metacognitive strategy training, compared to working memory training alone. Working memory training is a potentially effective educational intervention when provided in addition to school; however, future research will need to investigate ways to maintain academic improvements long term and to optimize metacognitive strategy training to promote far‐transfer.

Age of acquisition affects object recognition: evidence from visual duration thresholds

The impact of age of acquisition (AoA) on object recognition was explored in three experiments measuring visual duration threshold (VDT) for the identification of pictures labelled with early and late acquired names. Participants viewed briefly displayed images preceded and followed by a pattern mask. The minimum display duration required for correct identification was shorter for pictures labelled with early names than for those labelled with late names. In Experiments 2 and 3 we explored the effects of two forms of visual degradation on VDT for pictures with early and late acquired names. Both degradation by superimposed visual elements, and degradation by contrast reduction extended VDT, but only the former interacted with AoA. We conclude that both AoA and degradation by superimposed visual elements affect the efficiency of visual object recognition, but only degradation by contrast and not AoA affects the efficiency of earlier pre-recognition processes.

The role of cognitive factors in the pathogenesis of obsessive-compulsive symptoms: a prospective study

Cognitive models of obsessive-compulsive disorder (OCD) posit that specific kinds of dysfunctional beliefs (e.g., pertaining to responsibility and the significance of intrusive thoughts) underlie the development of this disorder. The present study was designed to prospectively evaluate whether dysfunctional beliefs thought to underlie OCD act as a specific vulnerability factor in the pathogenesis of obsessive-compulsive symptomatology. Eighty-five individuals were prospectively followed over a period of time thought to be associated with an increased onset of OCD symptoms -- childbirth and the postpartum. The majority of these new mothers and fathers experienced intrusive infant-related thoughts and performed neutralizing behaviors similar to, but less severe than, those observed in OCD. Scores on a measure of dysfunctional beliefs thought to underlie OCD predicted the development of obsessive-compulsive symptoms after controlling for pre-existing OCD symptoms, anxiety, and depression. Dysfunctional beliefs also predicted the severity of checking, washing, and obsessional OCD symptom dimensions, but not neutralizing, ordering, or hoarding symptom dimensions. These data provide evidence for specific dysfunctional beliefs as risk factors in the development of some types of OCD symptoms.     

Expectation of outgroup behaviour: can you trust the outgroup?

Outgroups are usually viewed with suspicion and expected to discriminate against the ingroup. The present study demonstrated that ingroup members attributed past discriminatory behaviour committed by individuals of unknown group membership more to outgroup members than to either ingroup members or members of a neutral group. In contrast, past egalitarian behaviour was attributed less to outgroup members than to members of a neutral group. Ingroup members also expected more discrimination from a future outgroup allocator than from a future neutral group allocator. Finally, the study showed that ingroup members' own behaviour in allocating money became more biased in favour of ingroup members vis-á-vis outgroup members when the future allocator was from an outgroup rather than from a neutral group and when they had witnessed the discriminatory behaviour of an allocator in the past.     

Stimulus spacing effects in duration perception are larger for auditory stimuli: Data and a model

Models of duration bisection have focused on the effects of stimulus spacing and stimulus modality. However, interactions between stimulus spacing and stimulus modality have not been examined systematically. Two duration bisection experiments that address this issue are reported. Experiment 1 showed that stimulus spacing influenced the classification of auditory, but not visual, stimuli. Experiment 2 used a wider stimulus range, and showed stimulus spacing effects for both visual and auditory stimuli, although the effects were larger for auditory stimuli. A version of Temporal Range Frequency Theory was applied to the data, and was used to demonstrate that the qualitative pattern of results can be captured with the single assumption that the durations of visual stimuli are less discriminable from one another than are the durations of auditory stimuli.     

ERNEST BECKER'S PSYCHOLOGY OF RELIGION FORTY YEARS ON: A VIEW FROM SOCIAL COGNITIVE PSYCHOLOGY

This article distinguishes between three projects in Ernest Becker's (1924–1974) later work: his psychology of “religion,” his psychology of religion, and his psychology of Religion (with a capital R). The first is an analysis of culture and civilization as immortality projects, means by which to deny death. The second, which overlaps with the first, is a characterization of religion‐as‐practiced (e.g., by adherents of the world religions) as a particularly effective immortality project vis‐à‐vis death anxiety. The third is less social scientific and more theological; Becker argues for a view of God that is in the tradition of Søren Kierkegaard and Paul Tillich (and, arguably, Pseudo‐Dionysius, Augustine, and Thomas Aquinas). Focusing on the second of these projects—as much has already been written on the first, and little can be said about the third—this article evaluates Becker's claims about religion‐as‐practiced in light of recent developments in social cognitive psychology.     

Crying threshold and intensity in major depressive disorder

Clinical lore suggests that depression is associated with frequent and intense crying. To test these postulations empirically, a standardized cry-evoking stimulus was presented to depressed and nondepressed participants, and their likelihood of crying and the magnitude of crying-related changes in their emotion experience, behavior, and autonomic physiology were compared. Unexpectedly, crying was no more likely in depressed than in nondepressed participants. Within the nondepressed group, participants who cried exhibited increases in the report and display of sadness and had greater cardiac and electrodermal activation than did participants who did not cry. There was less evidence of this crying-related emotional activation within the depressed group. The lack of emotional activation among clinically depressed participants who cried provides a tantalizing clue concerning how emotions are dysregulated in this disorder.     

Persistence and relapse of reinforced behavioral variability

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component of a multiple schedule. In the other component, food was delivered at the same rate, but without the lag variability requirement (i.e., yoked). Following extinction, levels of behavioral variability returned to baseline for both components after response‐independent food delivery (i.e., reinstatement). In Experiment 3, one group of pigeons responded on a lag variability schedule, and the other group responded on a lag repetition schedule. For both groups, levels of behavioral variability increased when alternative reinforcement was suspended (i.e., resurgence). In each experiment, we observed some evidence for extinction‐induced response variability and for variability as an operant dimension of behavior.
