Memory and aging in context

Much research has indicated that aging is accompanied by decrements in memory performance across a wide variety of tasks and situations. A dominant perspective is that these age differences reflect normative changes in the integrity and efficiency of the information-processing system. Contextual perspectives of development, however, argue for consideration of a broader constellation of factors as determinants of both intraindividual change and interindividual variation in memory functioning. The validity of the contextual perspective in characterizing the relationship between aging and memory is examined through a review of studies exploring a variety of alternative mechanisms associated with age differences in performance. It is concluded that a more multidimensional approach to the study of aging and memory is warranted.     

The timing of appraisals

The appraisal process consists of the subjective evaluation that occurs during an individual's encounter with significant events in the environment, determining the nature of the emotional reaction and experience. Placed in the context of appraisal theories of emotion-elicitation and differentiation, the aim of the present research was to test empirically the hypothesis that the intrinsic pleasantness evaluation occurs before the goal conduciveness evaluation. In two studies, intrinsically pleasant and unpleasant images were used to manipulate pleasantness, and a specific event in a Pacman-type videogame was used to manipulate goal conduciveness. Facial EMG was used to measure facial reactions to each evaluation. As predicted, facial reactions to the intrinsic pleasantness manipulation were faster than facial reactions to the goal conduciveness manipulation. These results provide good empirical support for the sequential nature of the appraisal process.     

Examination of a Regressive Prompt-Delay Procedure for Improving Sight-Word Reading

The current two-experiment study examined the effects of a regressive prompt-delay procedure on sight-word reading of four elementary school students. In contrast to traditional progressive prompt-delay procedures in which the latency of prompts is increased, the regressive prompt-delay latency is decreased over time. Data indicate that participants learned sight words quickly and maintained responding at high levels when instruction was withdrawn across both regressive and progressive prompt-delay conditions. Results are discussed in context of empirically supported prompting strategies and possible motivating operations that might be introduced when the learner is instructed to respond more quickly than the experimenter in regressive prompt delay (e.g., a game-like activity that potentially makes the activity educational, engaging, and enjoyable for students).     

Career and employer change in the age of the ‘boundaryless’ career

This study examined the direct effect of individual career concerns on career and employer change intention, as well as the buffering influence of organisational commitment on this relationship, based on the AMO model of behavioural change intention. Survey data, collected from 341 employees across industry sectors in Australia, showed that ‘exploration’ concerns related positively to both employer and career change intentions; the impact of exploration concerns on career change intention was buffered by affective commitment, however, and reinforced by normative commitment. ‘Establishment’ concerns related negatively to career change intention, and this effect was also buffered by level of affective commitment. The results point towards the distinct nature of employer and career change, and prompt calls for further research on the interplay of the myriad of factors that influence boundary-crossing career behaviour.
