Acquisition of a visual discrimination and reversal learning task by Labrador retrievers

Optimal cognitive ability is likely important for military working dogs (MWD) trained to detect explosives. An assessment of a dog’s ability to rapidly learn discriminations might be useful in the MWD selection process. In this study, visual discrimination and reversal tasks were used to assess cognitive performance in Labrador retrievers selected for an explosives detection program using a modified version of the Toronto General Testing Apparatus (TGTA), a system developed for assessing performance in a battery of neuropsychological tests in canines. The results of the current study revealed that, as previously found with beagles tested using the TGTA, Labrador retrievers (N = 16) readily acquired both tasks and learned the discrimination task significantly faster than the reversal task. The present study confirmed that the modified TGTA system is suitable for cognitive evaluations in Labrador retriever MWDs and can be used to further explore effects of sex, phenotype, age, and other factors in relation to canine cognition and learning, and may provide an additional screening tool for MWD selection.

The Impact of Modifying Interpretive Bias on Contamination-Related Obsessive–Compulsive Symptoms

Cognitive-behavioural models of obsessive–compulsive disorder (OCD) propose that a tendency to negatively interpret ambiguous thoughts and situations plays a key role in maintaining the disorder. Moreover, some researchers have proposed that negative interpretive biases may share a common processing mechanism with attentional biases, with changes in one predicted to lead to changes in the other. The current study examined whether training positive (i.e., adaptive) interpretive bias of contamination-related OCD concerns using a cognitive bias modification paradigm (CBM-I) would lead to reductions in contamination concerns, as well as changes in contamination-related attentional bias. Undergraduate students with high levels of contamination-related OCD symptoms were randomly assigned to receive either positive (n?=?31) or neutral (n?=?33) CBM-I training. Participants in the positive training condition, relative to the neutral training condition, showed a significantly greater increase in positive interpretive bias, significantly less within-session behavioural avoidance of contaminants, and significantly reduced contamination-related cognitions (at one-week follow-up). Contrary to expectations, CBM-I training did not differentially impact attentional bias nor self-reported contamination-related OCD symptoms. We discuss future directions in applying CBM-I to contamination-related OCD.

     

Risking Everything in Obsessive–Compulsive Disorder: An Analogue Decision-Making Study

An experiment examined decision-making processes among nonclinical participants with low or high levels of OCD symptomatology (N?=?303). To better simulate the decision environments that are most likely to be problematic for clients with OCD, we employed decision tasks that incorporated “black swan” options that have a very low probability but involve substantial loss. When faced with a choice between a safer option that involved no risk of loss or a riskier alternative with a very low probability of substantial loss, most participants chose the safer option regardless of OCD symptom level. However, when faced with choices between options that had similar expected values to the previous choices, but where each option had some low risk of a substantial loss, there was a significant shift towards riskier decisions. These effects were stronger when the task involved a contamination based, health-relevant decision task as compared to one with financial outcomes. The results suggest that both low and high symptom OC participants approach decisions involving risk-free options and decisions involving risky alternatives in qualitatively different ways. There was some evidence that measures of impulsivity were better predictors of the shift to risky decision making than OCD symptomatology.

Altered attention for stimuli on the hands

Attention operates in the space near the hands with unique, action-related priorities. Here, we examined how attention treats objects on the hands themselves. We tested two hypotheses. First, attention may treat stimuli on the hands like stimuli near the hands, as though the surface of the hands were the proximal case of near-hand space. Alternatively, we proposed that the surface of the hands may be attentionally distinct from the surrounding space. Specifically, we predicted that attention should be slow to orient toward the hands in order to remain entrained to near-hand space, where the targets of actions are usually located. In four experiments, we observed delayed orienting of attention on the hands compared to orienting attention near or far from the hands. Similar delayed orienting was also found for tools connected to the body compared to tools disconnected from the body. These results support our second hypothesis: attention operates differently on the functional surfaces of the hand. We suggest this effect serves a functional role in the execution of manual actions.     

Creative Imagination is Stable Across Technological Media: The Spore Creature Creator Versus Pencil and Paper

T. B. Ward (1994) investigated creativity by asking participants to draw alien creatures that they imagined to be from a planet very different from Earth. He found that participant drawings reliably contained features typical of common Earth animals. As a consequence, Ward concluded that creativity is structured. The present investigation predicts that this limitation on creativity is not restricted to drawings: the use of different technology will not change creative output. To investigate this question, participants performed Ward's task twice: once using pencil and paper and once using software made to design creatures (the Spore Creature Creator). Only minor significant differences were found. This preliminarily suggests that changing tools does not affect the overall rigidity of the creative process. This lends further support to Ward's thesis on the structural rigidity of creativity. We conclude by suggesting an elaboration to Ward's thesis that will be explored in future work. We suggest that aesthetics might be one of the factors that contribute to creative constraint, in that creatures that are too unusual would be less interesting.     

Shifty talk: knowledge and causation

In this paper, I criticise one main strategy for supporting anti-intellectualism, the view that whether a subject knows may depend on the stakes. This strategy appeals to difficulties with developing contextualist and pragmatic treatments of the shiftiness of our talk about knowledge to motivate anti-intellectualism. I criticise this strategy by drawing an analogy between debates about causation and knowledge. In each case, talk about a phenomenon is shifty and contextualist and pragmatic explanations of the shifty talk face the same objections. However, in the case of causation it would be implausible to argue that difficulties with the relevant contextualist and pragmatic accounts motivate a revisionary metaphysics of causation. I conclude that the defender of anti-intellectualism needs to employ a different strategy to defend her view.
