Not all semantics: Similarities and differences in reminiscing function and content between Indigenous and non-Indigenous Australians

This study explored why and how Indigenous and non-Indigenous Australians remember the past. Indigenous Australians traditionally share a strong oral tradition in which customs, personal and cultural histories, and other narratives are passed across groups and between generations by word of mouth. Drawing on this tradition, in which inherent value is placed on sharing knowledge and maintaining connectedness with others, we hypothesised that Indigenous Australians would be more likely than non-Indigenous Australians to report reminiscing to fulfil social functions (but not self or directive functions). Furthermore, we hypothesised that Indigenous Australians would recall personal past experiences more elaborately than would non-Indigenous Australians. In Study 1, 33 Indigenous Australians and 76 non-Indigenous Australians completed Webster's Reminiscence Functions Scale. As predicted, Indigenous participants reported higher scores on subscales related to social functions than did non-Indigenous Australians: particularly “Teach/Inform” and “Intimacy Maintenance”. They also scored higher on the “Identity” subscale. In Study 2, 15 Indigenous and 14 non-Indigenous Australians shared three memories from the distant and recent past. While Indigenous and non-Indigenous narratives did not differ in either emotion or elaboration, Indigenous Australians provided more memory context and detail by including a greater proportion of semantic memory content. Taken together, these findings suggest differences in both why and how Australians remember.     

The Effects of Stress on the Lives of Emerging Adult College Students: An Exploratory Analysis

This study systematically analyzed the personal reports of 20 emerging adult college students with regard to how stress affects their lives. Qualitative analyses revealed that stress influenced students' lives in both positive and negative ways. Implications of these findings for physical and mental health are discussed. Recommendations for counseling practice are provided.     

Serial killers,spiders and cybersex: Social and survival information bias in the transmission of urban legends

This study uses urban legends to examine the effects of the social information bias and survival information bias on cultural transmission across three phases of transmission: the choose‐to‐receive phase, the encode‐and‐retrieve phase, and the choose‐to‐transmit phase. In line with previous research into content biases, a linear transmission chain design with 60 participants aged 18–52 was used to examine the encode‐and‐retrieve phase, while participants were asked to rank their interest in reading the story behind a headline and passing a story on for the other two phases. Legends which contained social information (Social Type), legends which contained survival information (Survival Type), and legends which contained both forms of information (Combined Type) were all recalled with significantly greater accuracy than control material, while Social and Combined Type legends were recalled with significantly greater accuracy than Survival Type legends. In another study with 30 participants aged 18–22, no significant differences were found between legend types in either the choose‐to‐receive phase or the choose‐to‐transmit phase.     

Do chimpanzees (Pan troglodytes) understand single invisible displacement?

Previous research suggests that chimpanzees understand single invisible displacement. However, this Piagetian task may be solvable through the use of simple search strategies rather than through mentally representing the past trajectory of an object. Four control conditions were thus administered to two chimpanzees in order to separate associative search strategies from performance based on mental representation. Strategies involving experimenter cue-use, search at the last or first box visited by the displacement device, and search at boxes adjacent to the displacement device were systematically controlled for. Chimpanzees showed no indications of utilizing these simple strategies, suggesting that their capacity to mentally represent single invisible displacements is comparable to that of 18-24-month-old children.     

Getting hammered? ‥‥ students coping with alcohol

• This research draws on identity and coping theories to develop an understanding of the ways in which students with differing stances towards alcohol (both drinkers and light/non‐drinkers) deal with alcohol‐dominated social situations. We report findings from two studies, the first based on the stories of 160 students and the second based on in‐depth interviews with eight students. Our research found that many undergraduates view alcohol as playing a central role in ‘student life’, with excessive drinking being the norm. However, there is a significant group who are not comfortable with this view, nor do they ascribe to it. Choosing not to engage with the stereotypical student image presents a very real set of problems, stresses and barriers and the students discussed the various coping strategies they had in place to deal with these problems. We discuss the implications of these findings and the challenges for public policy in this area.

Motion perception in the ageing visual system: minimum motion, motion coherence, and speed discrimination thresholds

We aimed to address two issues: first, to describe how the perception of motion differs in elderly observers as compared to younger ones; and, second, to see if these changes in motion perception could be accounted for by the known changes in the ability of elderly observers to detect patterns (as indexed via contrast sensitivity). The lower threshold of motion, motion coherence, and speed discrimination were measured, alongside contrast sensitivity, in a group of thirty-two older (mean age 61.5 years) and thirty-two younger (mean age 23.2 years) subjects. The older observers showed losses in their ability to detect slow motions as indexed via the lower threshold of motion for random-dot patterns and for gratings of a range of spatial frequencies. They also were impaired on a test of motion coherence, but only for stimuli of a slow to medium speed, whereas faster speeds showed no decline with age. Finally, at all speeds tested the older observers required greater differences in speed in order to discriminate between patterns moving at different speeds. The pattern of losses on motion perception tasks was not predicted by the deficits of the older groups, such as loss of detection thresholds for high spatial and/or temporal frequencies. It is concluded that these hypotheses do not provide an adequate account of the data, and therefore that the losses occurring with age are complex and probably are a result of the loss of several types of cell.     

Processing mode influences the relationship between trait rumination and emotional vulnerability

Watkins (2004) found that the mode of processing adopted during expressive writing following a failure influenced emotional recovery from the failure as a function of level of trait rumination. At higher levels of trait rumination, negative mood 12 hours after the failure was greater, but only in an abstract, evaluative writing condition and not in a concrete, process-focused condition. The current study examined whether this interaction of trait rumination with processing mode would generalize to emotional vulnerability to a subsequent negative stressor. Participants repeatedly focused on both positive and negative scenarios in either a concrete, process-focused or an abstract, evaluative mode, before a failure experience. As predicted, after the failure experience, higher levels of trait rumination were associated with lower levels of positive affect, but only for participants in the abstract, evaluative condition and not for participants in the concrete, process-focused condition. This finding is consistent with processing mode influencing the relationship between trait rumination and emotional vulnerability.     

Cognitive style and depressive symptoms in elderly people - Extending the empirical evidence for the cognitive vulnerability-stress hypothesis

Introduction

Depression is common in older people and its identification and treatment has been highlighted as one of the major challenges in an ageing world. Poor physical and cognitive health, bereavement, and prior depression are important risk factors for depression in elderly people. Attributional or cognitive style has been identified as a risk factor for depression in children, adolescents and younger adults but its relevance for depression and mood in elderly people has not been investigated in the context of other risk factors.

Method

Sixty-four older adults from an ‘extra care’ living scheme (aged 59-97) were recruited for a 6-week prospective study to examine the relationships between cognitive style and depressive symptoms.

Results

Regression analyses revealed that, when other risk factors were controlled for, cognitive style and its interaction with stress predicted changes in depressive symptoms, therefore partially replicating prior research.

Conclusion

Cognitive-stress-vulnerability models also apply to elderly populations, but may be rather predictive of changes in depression when facing lower levels of stress.
