An effect of spatial-temporal association of response codes: understanding the cognitive representations of time

The present study addresses the question of how such an abstract concept as time is represented by our cognitive system. Specifically, the aim was to assess whether temporal information is cognitively represented through left-to-right spatial coordinates, as already shown for other ordered sequences (e.g., numbers). In Experiment 1, the task-relevant information was the temporal duration of a cross. RTs were shorter when short and long durations had to be responded to with left and right hands, respectively, than with the opposite stimulus-response mapping. The possible explanation that the foreperiod effect (i.e., shorter RTs for longer durations) is greater with right than with left hand responses is discarded by results of Experiment 2, in which right and left hand responses alternated block-wise in a variable foreperiod paradigm. Other explanations concerning manual or hemispheric asymmetries may be excluded based on the results of control experiments, which show that the compatibility effect between response side and cross duration occurs for accuracy when responses are given with crossed hands (Experiment 3), and for RTs when responses are given within one hand (Experiment 4). This pattern suggests that elapsing time, similarly to other ordered information, is represented in some circumstances through an internal spatial reference frame, in a way that may influence motor performance. Finally, in Experiment 5, the temporal duration was parametrically varied using different values for each response category (i.e., 3 short and 3 long durations). The compatibility effect between hand and duration was replicated, but followed a rectangular function of the duration. The shape of this function is discussed in relation to the specific task demands.

Informed Consent in Emergency Research: A Contradiction in Terms

Improving the treatment of life threatening emergency illness or disease requires that new or novel therapies be assessed in clinical trials. As most subjects for these trials will be incapacitated there is some controversy about they might best protected whilst still allowing research to continue. Recent European and UK clinical trials legislation, which has effectively stopped research into emergency conditions, is discussed. Possible changes to these regulations are proposed.     

Searching in the dark: Cognitive relevance drives attention in real-world scenes

We investigated whether the deployment of attention in scenes is better explained by visual salience or by cognitive relevance. In two experiments, participants searched for target objects in scene photographs. The objects appeared in semantically appropriate locations but were not visually salient within their scenes. Search was fast and efficient, with participants much more likely to look to the targets than to the salient regions. This difference was apparent from the first fixation and held regardless of whether participants were familiar with the visual form of the search targets. In the majority of trials, salient regions were not fixated. The critical effects were observed for all 24 participants across the two experiments. We outline a cognitive relevance framework to account for the control of attention and fixation in scenes.     

Attributing “Third World Poverty” in Australia and Malawi: A Case of Donor Bias?1

Causal attributions for poverty in the developing world were examined from the perspectives of “actors” living in a “developing country” (Malawi) and “observers” living in a “developed country” (Australia). Ninety‐eight Malawian and 100 Australian weekend shoppers responded to the Causes of Third World Poverty Questionnaire (CTWPQ) and the Just World Scale (JWS), with Australian participants also providing information about their frequency of donating to foreign‐aid charities. Consistent with the actor–observer bias, Australians were more likely than were Malawians to attribute poverty to dispositional characteristics of the poor, rather than to situational factors. Among the Australians, situational attributions were in turn associated with frequency of donation behavior. The finding of a donor bias in this sample has important implications for the social marketing of foreign aid to Western donor publics.     

Computer-Assisted Careers Guidance Systems as Decision Support Systems

'Decision support systems' are computer systems which are aimed at improving decisions made by managers. An examination of the literature on decision support systems suggests that there are similarities between these systems and computer-aided careers guidance systems. These similarities —and differences -are explored, and a number of ways in which each approach might learn from the other are suggested.     

The group-as-a-whole approach in Foulksian group analytic psychotherapy

The group analytic group-as-a-whole approach of Foulkes privileges the concept of the group matrix. The term matrix is a metaphor for the network of all individual mental processes, the psychological medium in which they meet, communicate, and interact. The developing group matrix acts both as a container and as a holding environment for the psychic processes of the individual members in the group context. The concept of coherency is evoked to describe the process of the developing capacity of a group to be therapeutic. The concept of coherency is applied both to conscious and to unconscious mental process.     

Panic disorder in the families of patients with normal coronary arteries and non-fear panic disorder.

Patients with non-fear panic disorder (NFPD) meet DSM-III-R criteria for panic disorder, but do not report subjective fear or anxiety. Although apparently common in medical settings, this controversial group is in need of further diagnostic validation. This study assessed family history of panic disorder in patients with chest pain and normal coronary arteries (CP/NCA) and either NFPD, panic disorder with fear, or no panic. It was hypothesized that the two panic disorder groups would have similar, elevated rates of panic disorder in their first-degree relatives, compared to patients without panic. The results support the hypothesis; about 17% of the first-degree relatives of both NFPD and panic disorder patients were diagnosable with panic disorder according to proband interviews, whereas only 4.6% of the first-degree relatives of patients without panic were so diagnosable. These results support the diagnostic validity of NFPD in CP/NCA patients, because such patients had a family history of panic disorder similar to patients with a more classical panic disorder presentation. The lack of fear symptoms and behavior in NFPD may cause panic disorder to be overlooked as a potential cause of somatic symptoms in patients with no medical explanation for their condition.
