Direct and generative autobiographical memory retrieval: How different are they?

Theories of autobiographical memory have emphasised effortful generative retrieval, but recent research indicates that subjectively effortless direct retrieval is common. We compared the processes of direct and generative retrieval. Sixty-five participants retrieved 24 autobiographical memories across three cue types: concrete, emotional, and personal. We recorded retrieval latency, and participants judged direct versus generative retrieval and rated memory specificity, vividness, significance, rehearsal, and emotionality. Overall, direct retrieval was common, especially for personal cues. Directly retrieved memories were recalled faster, were less likely to be specific, and were rated more significant, rehearsed, and emotional than generatively retrieved memories. The speed of both direct and generative retrieval varied similarly according to cue type, suggesting they did not involve fundamentally different cognitive processes. These findings challenge theories that assume direct retrieval bypasses constructive processes. Instead we suggest that both direct and generative retrieval involve construction that is similarly affected by cue concreteness and relevance.     

Number and language: how are they related?

Does the ability to develop numerical concepts depend on our ability to use language? We consider the role of the vocabulary of counting words in developing numerical concepts. We challenge the 'bootstrapping' theory which claims that children move from using something like an object-file - an attentional process for responding to small numerosities - to a truly arithmetic one as a result of their learning the counting words. We also question the interpretation of recent findings from Amazonian cultures that have very restricted number vocabularies. Our review of data and theory, along with neuroscientific evidence, imply that numerical concepts have an ontogenetic origin and a neural basis that are independent of language.     

Parental belief and parental engagement: how do they interact?

Previous literature has shown the importance of parental engagement for children’s outcomes; a largely separate body of literature has shown that there are clear effects on children’s outcomes related to parental religion. This article is a literature review of these two fields, with the aim of relating them to each other. The article suggests two possible explanations, behavioural and economic, for the differences in outcomes related to differences in parental engagement arising from differences in religion, but incorporating knowledge from the field of parental engagement. Finally, it sets out a research agenda for the future.     

Religion and medicine: How are they related?

This paper provides a comprehensive and dynamic profile of religion-medicine interrelationships. This profile is drawn from the respective characteristics of religion and medicine, as well as from historic and contemporary literature regarding their interconnections. Six symbiotic functions are identified and discussed with respect to their bearing on clinical practice, medical education, and research.The authors thank Drs. Chester R. Burns, Thomas H. Murray, and Ronald A. Carson for their comments on drafts of this paper.     

Performance expectations,personal resources,and job resources: How do they predict work engagement?

Research on work engagement has mainly focused on the role of job and personal resources and has ignored the possible impact of personal demands workers develop with regard to their work. The aim of our study was to test the reciprocal relationships that job resources, personal resources, and personal demands, operationalized as performance expectations, share with work engagement. Three-wave longitudinal data were collected in a Belgian public institution (N?=?473). Results confirm the causal effects of job resources, personal resources, and performance expectations on work engagement. Reciprocal relationships are not significant. Results are discussed with regard to the impact of changes in job and personal resources and performance expectations on work engagement. Practical implications including reinforcement of Human Resources practices such as appraisal interviewing and career management are also discussed.     

How similar are recognition memory and inductive reasoning?

Conventionally, memory and reasoning are seen as different types of cognitive activities driven by different processes. In two experiments, we challenged this view by examining the relationship between recognition memory and inductive reasoning involving multiple forms of similarity. A common study set (members of a conjunctive category) was followed by a test set containing old and new category members, as well as items that matched the study set on only one dimension. The study and test sets were presented under recognition or induction instructions. In Experiments 1 and 2, the inductive property being generalized was varied in order to direct attention to different dimensions of similarity. When there was no time pressure on decisions, patterns of positive responding were strongly affected by property type, indicating that different types of similarity were driving recognition and induction. By comparison, speeded judgments showed weaker property effects and could be explained by generalization based on overall similarity. An exemplar model, GEN-EX (GENeralization from EXamples), could account for both the induction and recognition data. These findings show that induction and recognition share core component processes, even when the tasks involve flexible forms of similarity.     

Semantic and perceptual priming: how similar are the underlying mechanisms?

Both semantic priming and perceptual priming consist of facilitation of the identification of primed stimuli and inhibition of the identification of nonprimed stimuli. The similarities between the two phenomena suggest that a common attentional mechanism underlies both, and this has been explicitly proposed by several attention theorists. In this article it is argued that the phenomena of semantic and perceptual priming are qualitatively different, perceptual priming reflecting a sensitivity change in the recognition process brought about by attention, and semantic priming reflecting a bias change in the recognition process brought about by attention. Because different mechanisms are required to produce sensitivity and bias changes, this implies that the attentional mechanisms responsible for semantic and perceptual priming are distinct. In terms of recent discussions of the modularity versus the unity of cognitive architecture, the present conclusion supports a modular architecture for attentional processes.     

Scientific societies and research integrity: What are they doing and how well are they doing it?

Scientific societies can play an important role in promoting ethical research practices among their members, and over the past two decades several studies have addressed how societies perform this role. This survey continues this research by examining current efforts by scientific societies to promote research integrity among their members. The data indicate that although many of the societies are working to promote research integrity through ethics codes and activities, they lack rigorous assessment methods to determine the effectiveness of their efforts. An earlier version of this paper was presented at the AAAS-Office of Research Integrity (ORI) meeting in Washington DC on the theme: “The Role and Activities of Scientific Societies in Promoting Research Integrity” held on April 10–11, 2000.     

What is the best way to promote cycling? A systematic review and meta-analysis

Cycling has the potential to address a number of personal and societal challenges, not least with respect to health and the need for more sustainable modes of transport. However, the best way(s) to promote cycling is still unclear. In an effort to answer this question, we identified 39 interventions designed to promote cycling, with a total sample of 46,102 participants. Random effects meta-analysis estimated a small but statistically significant effect of interventions on cycling behaviour (g₊ = 0.14, 95% CI [0.05, 0.23]). To identify the most effective intervention strategies, we coded the behaviour change techniques used within each of the interventions. Interventions that prompted people to self-monitor their behaviour or added objects to the environment (e.g., provided shared bikes) were more effective than those that did not use these strategies. Interventions that restructured the physical environment (e.g., built new cycle paths) were less effective than the studies that did not do this. We also identified a number of factors that moderated the effect of the interventions on outcomes; specifically, interventions that targeted a specific group, used objective measures of cycling such as accelerometers, and that were tested using independent groups designs typically yielded stronger effects. The findings should help to guide interventions to promote cycling in the future.     

Psychological universals: what are they and how can we know?

Psychological universals, or core mental attributes shared by humans everywhere, are a foundational postulate of psychology, yet explicit analysis of how to identify such universals is lacking. This article offers a conceptual and methodological framework to guide the investigation of genuine universals through empirical analysis of psychological patterns across cultures. Issues of cross-cultural generalizability of psychological processes and 3 cross-cultural research strategies to probe universals are considered. Four distinct levels of hierarchically organized universals are possible: From strongest to weakest claims for universality, they are accessibility universals, functional universals, existential universals, and nonuniversals. Finally, universals are examined in relation to the questions of levels of analysis, evolutionary explanations of psychological processes, and management of cross-cultural relations.     

Functional and dysfunctional perfectionists: are they different on compulsive-like behaviors?

Both perfectionism and excessive responsibility have been linked to obsessive compulsive disorder (OCD). Up to now however, a greater number of studies have focused on the role of responsibility. The present study compared compulsive-like behavior of people with different styles of perfectionism. Sixteen functional perfectionists (FP) and 16 dysfunctional perfectionists (DP) were compared on three different tasks in order to explore OC type behavior such as doubting, checking and intrusions. Results show that DP participants, compared to FP participants, scored higher on an OC behavior scale, took significantly more time to complete a precision task and precipitated their decision when confronted with ambiguity. The two groups also tended to differ in their intrusive thoughts following an unsolved problem; FP participants were more preoccupied about solving the problem than about the quality of their performance, contrary to DP subjects. Results are discussed according to theoretical models of OCD.     

Metaphors: How are they different for the poet,the child and the everyday adult?

This paper considers differences and similarities in the way children, poets and everyday adults make and understand metaphors. Samuel Levin (1976, in Pragmatics of language and literature, Amsterdam: North Holland Publishers; and 1979, in Metaphor and thought, Cambridge: Cambridge University Press) has argued that metaphors involve changing concepts of the world rather than shifts in word meanings. His theory rests on the idea that metaphors are to be understood literally and that the poem is a kind of speech act containing an implicit invitation for the reader to enter the poet's world. Werner's (1948, The comparative psychology of mental development, New York: International Universities Press) theory of physiognomic perception is discussed in order to show how childrens' as well as poet's metaphors are meant to be taken literally. While the meaning structure underlying adult and child metaphors is similar the intentionality and boundaries of use may differ for young children. Goffman's (1974, Frame analysis, New York: Harper and Row) theory of frames in discourse is presented in order to explore contexts other than poems in which a metaphor user might issue an invitation for a listener to enter his or her world.     

A systematic review and meta-analysis of cognitive-behavioural interventions to reduce problem gambling: Hedging our bets?

Problem gambling is of serious public, social and clinical concern, especially so because ease of access to different types of gambling is increasing. A systematic review and meta-analysis was carried out to determine whether Cognitive-Behavioural Therapies (CBT) were effective in reducing gambling behaviour. Twenty-five studies which met the inclusion criteria were identified. Overall, there was a highly significant effect of CBT in reducing gambling behaviours within the first three months of therapy cessation regardless of the type of gambling behaviour practiced. Effect sizes were also significant at six, twelve and twenty-four month follow-up periods. Sub-group analysis suggested that both individual and group therapies were equally as effective in the 3 month time window, however this equivalence was not clear at follow-up. All variants of CBT (cognitive therapy, motivational interviewing and imaginal desensitization) were significant, although there was tentative evidence that when different types of therapy were compared cognitive therapy had an added advantage. Meta-regression analyses showed that the quality of the studies influenced the effect sizes, with those of poorer quality having greater effect sizes. These results give an optimistic message that CBT, in various forms, is effective in reducing gambling behaviours. However, caution is warranted because of the heterogeneity of the studies. Evaluation of treatment for problem gambling lags behind other fields and this needs to be redressed in the future.     

Involuntary autobiographical memories in and outside the laboratory: How different are they from voluntary autobiographical memories?

In two studies, we compared the characteristics and retrieval times of involuntary and voluntary autobiographical memory under controlled laboratory conditions. A new laboratory task of involuntary autobiographical memories involved detecting vertical lines in a stream of stimuli with horizontal lines (an undemanding vigilance task) and recording any involuntary memories during the session. The majority of these memories were reported as being triggered by irrelevant cue phrases presented on the screen. Voluntary autobiographical memories were sampled via a standard word-cue method in Session 2. The results showed that involuntary memories were more specific and were retrieved significantly faster than voluntary memories. They were also more likely to be triggered by negative cues, whereas cue valence did not have any effect on the number of voluntary memories. Furthermore, laboratory involuntary memories did not differ from naturalistic involuntary memories recorded in a diary by the same participants (Study 2). Taken together, these results have important implications for current theories of autobiographical memory, and they open up interesting avenues for future research.     

Dementia and agitation in nursing home residents: how are they related?

The link between agitated behaviors and cognitive functioning in 408 nursing home residents was examined. Results showed that cognitively impaired residents manifested aggressive behaviors (e.g., cursing, hitting) and physically nonaggressive behaviors (e.g., pacing). The highest levels of physically nonaggressive behaviors were manifested by those residents who presented intermediate levels of impairment in their performance of activities of daily living. Cognitively intact residents exhibited verbally agitated behaviors (e.g., complaining). These findings have important implications for caregivers of agitated nursing home residents.
