Motivation and memory in zebra finch (<Emphasis Type="Italic">Taeniopygia guttata</Emphasis>) foraging behavior

Remembering combinations of information such as what resources have been seen in which locations could play an important role in enhancing individual survival through increased foraging success. To date, there have been relatively few investigations of avian memory involving more than one category of information. This study explored zebra finches’ (Taeniopygia guttata) capacity to recall two categories in combination, namely food-type and spatial location. Birds were trained to remove variously weighted flaps to find two types of food hidden beneath. Memory for food-types and locations was assessed by pre-feeding the birds to satiety on and devaluing one food-type, and then testing the birds’ efficiency at finding the non-devalued food. When allowed one trial to learn locations of two food rewards that were hidden beneath lightly weighted flaps, birds performed better than chance at locating a food reward. However, they did not preferentially search for the non pre-fed food, suggesting that they were unable to recall both food type and location in combination. Zebra finches made fewer errors when tested on the one-trial task using more heavily weighted flaps than with lightly weighted flaps; there was equivocal evidence that they remembered which food type was hidden where on this task. When given repeated exposures to the locations of the two food rewards, finches located a food reward more accurately than on the one-trial tasks, and were also more likely to recall the locations of the different food types. In this foraging paradigm, experience and motivation may have influenced the birds’ performance.     

On the dynamic information underlying visual anticipation skill

What information underwrites visual anticipation skill in dynamic sport situations? We examined this question on the premise that the optical information used for anticipation resides in the dynamic motion structures, or modes, that are inherent in the observed kinematic patterns. In Experiment 1, we analyzed whole-body movements involved in tennis shots to different directions and distances by means of principal component analysis. The shots differed in the few modes that captured most of the variance, especially as a function of shot direction. In Experiments 2 and 3, skilled and less skilled tennis players were asked to anticipate the direction of simulated shots on the basis of kinematic patterns in which only the constituent dynamic structures were manipulated. The results indicated that players predicted shot direction by picking up the information contained in multiple low-dimensional dynamic modes, suggesting that anticipation skill in tennis entails the extraction of this dynamic information from high-dimensional displays.     

Effect of a 9-wk. after-school multiskills club on fundamental movement skill proficiency in 8- to 9-yr.-old children: an exploratory trial

This exploratory study examined the effects of a 9-wk. after-school multiskills club on fundamental movement skill proficiency in 8- to 9-yr.-old children. Two schools were randomly assigned to either a control (n = 15 children) or multiskill club (n = 19 children) condition. The multiskill club received 18 coaching sessions designed to improve fundamental movement skills. The control group followed normal routines. 7 skills were assessed using process-oriented measures with video analysis. Participation in the multiskill club yielded significant improvements in proficiency at posttest only in static balance, while potentially practically important improvements were observed in performance of the catch, throw, and kick skills. The after-school multiskill club offered a viable opportunity for movement skill acquisition, but any such programme would need to run for a longer duration to assess whether this type of activity could benefit all skills.     

Does the covert nature of caring prohibit the development of effective services for young carers?

Almost 3 million children in the UK live in households where at least one family member is affected by chronic illness or disability. A proportion of these children will be young carers. This paper begins with a brief review of the literature relating to young carers. Particular attention is paid to the adoption of a caring role, the'hidden' nature of caring including young people'sreluctance to discuss their caring, the impact of caring on education, and the location and type of services provided.The findings of a small-scale study carried out in Scotland are presented in order to highlight some of the issues raised in the literature. Discussion focuses on the implications for the field of guidance and counselling.     

Gender-Linked Differences in Everyday Memory Performance: Effort Makes the Difference

Previous research has found gender differences in everyday memory tasks such as remembering shopping lists or directions, and these findings can be attributed to increased motivation or memory skill resulting from the association of different tasks with masculine or feminine gender roles. To investigate the motivational explanation, the recall of an ambiguous shopping list, labeled as grocery or hardware, was examined under instructions that stated that either women or men are good at the task, or instructions that were neutral. The findings were not consistent with the skill explanation. There was a significant interaction between list label, participant gender, and instructions, which can be explained in terms of the increased or decreased motivation that might arise from particular combinations of label and instruction.     

Efficacy of constant time delay implemented by peer tutors in general education classrooms

We evaluated the effects of teaching 13 typically developing children to use constant time delay when tutoring three of their peers who had substantial disabilities. We measured the extent to which the tutors used the constant time delay procedure correctly and the tutees' correct performance on the skills being taught. A multiple probe design across behaviors was used. The results indicated that (a) the tutors used each step of the constant time delay with a high degree of procedural fidelity; (b) the students with disabilities acquired the skills that were taught during peer tutoring; and (c) modifications of the procedure were required for 2 of the 3 students with disabilities, and the peers tutors were able to implement the modifications. Implications for practice and future research are described.     

Effectiveness of a brief group RET treatment for divorce-related dysphoria

This study evaluated the effectiveness of a brief, group rational-emotive (RET) treatment and problem solving treatment for divorce related dysphoria, involving six hours of therapy over 22 days. A waiting list condition was used for comparison. On three measures of dysphoria, RET and Problem-Solving subjects improved significantly more than Waiting List subjects and RET and Problem-Solving subjects maintained their improvement at a one-month follow-up. There was no significant difference in improvement between RET and Problem-Solving treatments. Effectiveness of the treatments could have been due either to specific content, group therapy components, or nonspecific effects.John Malouff is a clinical psychologist with the Rehabilitation Center of Palm Beach, Florida.

Investigating the relationship between product involvement and consumer decision‐making styles

• Recently, a number of studies have investigated consumer decision‐making styles (CDMS) and their importance to consumer behaviour research. However, research designs suggested to date are mainly replications of a study by Sproles and Kendall ( 1986 ) proposing eight mental characteristics, the so‐called Consumer Styles Inventory (CSI). The CSI has been applied across cultures, but without critically examining its validity and reliability. A major concern is the postulated product independence of CSI. The aim of this study is to further develop this approach, to apply it to different product categories and to investigate the relationship between product involvement and CDMS. In doing so, we conducted a survey in Great Britain and Germany, and analysed the data using exploratory and confirmatory factor analysis. Not only did we demonstrate that there is a relationship between products and CDMS, but also that CDMS are governed by consumers' perceived product involvement. Important implications for marketing practice can be derived.
