Differential effects of age on prospective and retrospective memory tasks in young, young-old, and old-old adults.

Remembering to do something in the future (termed prospective memory) is distinguished from remembering information from the past (retrospective memory). Because prospective memory requires strong self-initiation, Craik (1986) predicted that age decrements should be larger in prospective than retrospective memory tasks. The aim of the present study was to assess Craik's prediction by examining the onset of age decline in two retrospective and three prospective memory tasks in the samples of young (18-30 years), young-old (61-70 years), and old-old (71-80 years) participants recruited from the local community. Results showed that although the magnitude of age effects varied across the laboratory prospective memory tasks, they were smaller than age effects in a simple three-item free recall task. Moreover, while reliable age decrements in both retrospective memory tasks of recognition and free recall were already present in the young-old group, in laboratory tasks of prospective memory they were mostly present in the old-old group only. In addition, older participants were more likely to report a retrospective than prospective memory failure as their most recent memory lapse, while the opposite pattern was present in young participants. Taken together, these findings highlight the theoretical importance of distinguishing effects of ageing on prospective and retrospective memory, and support and extend the results of a recent meta-analysis by Henry, MacLeod, Phillips, and Crawford (2004).

Effective regulation of the experience and expression of negative affect in old age.

We investigated age differences in the experience and expression of emotion in 64 younger and 62 older adults. By manipulating emotion-regulation instructions, we investigated the effects of age on the control of both the inner experience and the outward expression of emotion. We predicted that there would be age improvements in regulating the inner experience of emotion. Indeed, our results indicated that older adults were more effective than young adults in following instructions to reduce the early experience of negative emotion. There were no age differences in following another emotion-regulation strategy involving the suppression of emotional display. In contrast to the well-documented difficulties in cognitive regulation of other studies, these data suggest that the ability to control experience and expression of emotions operates effectively in older adulthood.

Multiple-target tracking: A role for working memory?

In order to identify the cognitive processes associated with target tracking, a dual-task experiment was carried out in which participants undertook a dynamic multiple-object tracking task first alone and then again, concurrently with one of several secondary tasks, in order to investigate the cognitive processes involved. The research suggests that after designated targets within the visual field have attracted preattentive indexes that point to their locations in space, conscious processes, vulnerable to secondary visual and spatial task interference, form deliberate strategies beneficial to the tracking task, before tracking commences. Target tracking itself is realized by central executive processes, which are sensitive to any other cognitive demands. The findings are discussed in the context of integrating dynamic spatial cognition within a working memory framework.

A new conceptualization of alexithymia in the general adult population: implications for research involving older adults.

OBJECTIVE: The purpose of this study is to test the validity of existing conceptualizations of the alexithymia concept, with particular reference to aging. METHODS: Two hundred and forty-eight healthy adults completed measures of alexithymia and psychosocial functioning; younger and older adults (n=121) also completed a measure of emotional responsiveness. RESULTS: Older adults engaged in less introspective thought traditionally thought to denote increased alexithymia. However, reduced introspection was associated with improved mental wellbeing, and, thus, could not be construed as a deficit. Difficulty identifying and describing emotions did not differentiate older and younger adults, but were both associated with heightened depression, anxiety, and poor perceived quality of life. CONCLUSIONS: In clinical practice and research, the Toronto Alexithymia Scale (TAS) is almost exclusively used, with "total" score typically used to index alexithymia. As one of the subscales of the TAS measures reduced introspection, calculating total scores may not be appropriate and may particularly overestimate levels of alexithymia in older adulthood.

Social norms and self-presentation: children's implicit and explicit intergroup attitudes.

Two studies examined whether social norms and children's concern for self-presentation affect their intergroup attitudes. Study 1 examined racial intergroup attitudes and normative beliefs among children aged 6 to 16 years (n=155). Accountability (i.e., public self-focus) was experimentally manipulated, and intergroup attitudes were assessed using explicit and implicit measures. Study 2 (n = 134) replicated Study 1, focusing on national intergroup attitudes. Both studies showed that children below 10 years old were externally motivated to inhibit their in-group bias under high public self-focus. Older children were internally motivated to suppress their bias as they showed implicit but not explicit bias. Study 1, in contrast to Study 2, showed that children with low norm internalization suppressed their out-group prejudice under high public self-focus.

Remembering or knowing others? Person recognition and recollective experience.

Using Tulving's (1985) remember/know procedure, the present research investigated the experiential concomitants of person recognition. Noting basic differences in the manner in which the mind processes expectancy-related material, it was anticipated that facial typicality would be a critical determinant of people's recollective experiences (i.e., remembering vs knowing). In particular, it was expected that whereas remember responses would be more prevalent for distinctive than typical faces, know responses would reflect the opposite pattern. The results of two experiments provided general support for these predictions. In addition, the recollective advantage for distinctive faces was traced to the availability of attentional resources at encoding. These results are considered in the context of contemporary issues in person recognition and social cognition.

Self-esteem and memory.

This article describes two potential bases for memory bias associated with global self-esteem. According to the mood-congruence model, activation of either dimension of self-esteem (self-competence or self-liking) produces an affective state that facilitates retrieval of traces that are consistent with that state while hindering retrieval of traces that are inconsistent. According to the relevance model, activation of either dimension results in superior encoding of matching negative content by individuals who are low on the dimension. Three studies were conducted to determine which model best accounts for the pattern of bias across distinct content categories. Results were generally consistent with the relevance model.

Person perception across the menstrual cycle: hormonal influences on social-cognitive functioning.

Women's reactions to men shift during the menstrual cycle. For example, during the phase of high conception risk, women prefer men with masculinized facial features. A favored explanation for this effect is that women display an enhanced sensitivity to stimuli that have significant reproductive relevance during the phase of the menstrual cycle in which conception risk is high. Consistent with this viewpoint, the present research demonstrated that women's cycle-dependent attentiveness to "maleness" also extends to basic aspects of the person-perception process. Specifically, during the phase of high conception risk, women displayed an enhanced ability both to categorize men and to access associated category-related (i.e., stereotypic) material from semantic memory. The implications of these findings for contemporary treatments of person perception are considered.

Directed remembering: subliminal cues alter nonconscious memory strategies.

Much research on memory function has focused on changes in recognition performance brought about by differences in the processes engaged during encoding. In most of this work, participants either receive explicit instructions to remember particular items or they perform orienting (i.e., encoding) tasks that support different levels of memory performance. In daily life, however, the retention or dismissal of information often occurs without conscious intent, thereby suggesting an alternative, nonconscious route through which purposive remembering and forgetting can occur. Based on this line of reasoning, we speculated that recognition performance in a standard item-based forgetting paradigm may be moderated by subliminal cues that trigger the automatic activation of different mnemonic strategies. We report the results of two experiments that supported this prediction. In each experiment, the basic item-based forgetting effect was replicated, but via the subliminal presentation of "remember" and "forget" cues. In addition, cue-dependent differences in memory performance were traced to the operation of a covert rehearsal mechanism during encoding. We consider the implications of these findings for the non-conscious#10; operation of memory processes in everyday life.

Are you looking at me? Eye gaze and person perception.

Previous research has highlighted the pivotal role played by gaze detection and interpretation in the development of social cognition. Extending work of this kind, the present research investigated the effects of eye gaze on basic aspects of the person-perception process, namely, person construal and the extraction of category-related knowledge from semantic memory. It was anticipated that gaze direction would moderate the efficiency of the mental operations through which these social-cognitive products are generated. Specifically, eye gaze was expected to influence both the speed with which targets could be categorized as men and women and the rate at which associated stereotypic material could be accessed from semantic memory. The results of two experiments supported these predictions: Targets with nondeviated (i.e., direct) eye gaze elicited facilitated categorical responses. The implications of these findings for recent treatments of person perception are considered.

Decomposing global self-esteem.

We argue in this paper for distinguishing two dimensions of global self-esteem, self-competence and self-liking. Studies 1 and 2 identify a corresponding pair of factors in Rosenberg's (1965) Self-Esteem Scale. Studies 3 and 4 examine the predictive value of the two-dimensional approach to self-esteem as reflected in the unique associations of self-competence and self-liking with negative life events and word recognition.

Creating memory illusions: expectancy-based processing and the generation of false memories.

The present research investigated the generation of memory illusions. In particular, it attempted to delineate the conditions under which category-based thinking prompts the elicitation of false memories. Noting fundamental differences in the manner in which expected and unexpected person-related information is processed and represented in the mind, it was anticipated that, via gist-based recognition, participants would display a pronounced propensity to generate expectancy-consistent false memories. The results of three experiments supported this prediction. In addition, the research revealed that participants' false memories were accompanied by the subjective experience of knowing (Expt. 2) and that false recognition was exacerbated under conditions of executive dysfunction (Expt. 3). We consider the theoretical implications of these findings for recent treatments of memory illusions and social cognition.

Conceptual and perceptual processes in prospective remembering: differential influence of attentional resources.

Does prospective remembering rely on strategic, attentionally demanding processes? We report three experiments suggesting that the extent to which attentional processes are required varies according to the character of ongoing task processing. Study-test changes in the semantic context of targets had a negative effect on prospective memory performance when participants were engaged in a conceptually focused (sentence verification) task (Experiment 1). Similarly, prospective remembering was lower following study-test changes in perceptual format (font) in the context of a perceptually focused (readability rating) ongoing task (Experiment 2). However, although dividing attention at retrieval had a negative effect during the performance of an ongoing conceptual task (Experiments 1 and 3), it had no effect during an ongoing perceptual task (Experiments 2 and 3). Thus, both perceptual and conceptual process are implicated in prospective remembering, but the processing focus of the task in which remembering should occur may mediate the requirement for strategic processes. These findings suggest that more than one retrieval route is available for prospective remembering and that selection of the route depends on the nature of the task and the processing that occurs at encoding and retrieval.
