Death and the Self

It is an old philosophical idea that if the future self is literally different from the current self, one should be less concerned with the death of the future self (Parfit, 1984 ). This paper examines the relation between attitudes about death and the self among Hindus, Westerners, and three Buddhist populations (Lay Tibetan, Lay Bhutanese, and monastic Tibetans). Compared with other groups, monastic Tibetans gave particularly strong denials of the continuity of self, across several measures. We predicted that the denial of self would be associated with a lower fear of death and greater generosity toward others. To our surprise, we found the opposite. Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than any other group about the prospect of giving up a slightly longer life in order to extend the life of another.     

Suicide Protective Factors in Outpatient Substance Abuse Patients: Religious Faith and Family Support

The purpose of this study was to identify the protective roles of religious faith and family support in buffering against suicidal behavior in a sample of substance abuse outpatients seeking treatment. Data were collected from 112 clinical outpatients seeking treatment for substance abuse. We hypothesized that religious faith would be related to lower levels of suicidal behavior through a negative association with depressive symptoms. We expected this mediation effect would differ across varying levels of family support, providing support for a moderated mediation effect. The results indicate that religious faith exerts stronger direct and indirect effects on suicidal behavior at low levels of family support. Religious faith was significantly and negatively related to suicidal behavior only at low levels of family support. The findings suggest that in the absence of family support, religious faith may play a compensatory role in protecting against suicidal behavior.     

Effects of cognitive load on neural and behavioral responses to smoking-cue distractors

Smoking cessation failures are frequently thought to reflect poor top-down regulatory control over behavior. Previous studies have suggested that smoking cues occupy limited working memory resources, an effect that may contribute to difficulty achieving abstinence. Few studies have evaluated the effects of cognitive load on the ability to actively maintain information in the face of distracting smoking cues. For the present study, we adapted an fMRI probed recall task under low and high cognitive load with three distractor conditions: control, neutral images, or smoking-related images. Consistent with a limited-resource model of cue reactivity, we predicted that the performance of daily smokers (n = 17) would be most impaired when high load was paired with smoking distractors. The results demonstrated a main effect of load, with decreased accuracy under high, as compared to low, cognitive load. Surprisingly, an interaction revealed that the effect of load was weakest in the smoking cue distractor condition. Along with this behavioral effect, we observed significantly greater activation of the right inferior frontal gyrus (rIFG) in the low-load condition than in the high-load condition for trials containing smoking cue distractors. Furthermore, load-related changes in rIFG activation partially mediated the effects of load on task accuracy in the smoking-cue distractor condition. These findings are discussed in the context of prevailing cognitive and cue reactivity theories. These results suggest that high cognitive load does not necessarily make smokers more susceptible to interference from smoking-related stimuli, and that elevated load may even have a buffering effect in the presence of smoking cues under certain conditions.

Children's counterfactual inferences about long and short causal chains

Recent findings on counterfactual reasoning in children have led to the claim that children's developing capacities in the domain of ‘theory of mind’ might reflect the emergence of the ability to engage in counterfactual thinking over the preschool period (e.g. Riggs, Peterson, Robinson & Mitchell, 1998 ). In the study reported here, groups of 3- and 4-year old children were presented with stories describing causal chains of several events, and asked counterfactual thinking tasks involving changes to different points in the chain. The ability to draw successful counterfactual inferences depended strongly on the inferential length of the problem, and the age of the children; while 3-year-olds performed above chance on short inference counterfactuals, they performed below chance on problems involving longer inference chains. Four-year-old children were above chance on all problems. Moreover, it was found that while success on longer chain inference problems was significantly correlated with the ability to pass tests of standard false belief, there was no such relationship for short inference problems, which were significantly easier than false belief problems. These results are discussed in terms of the developmental relationships between causal knowledge, counterfactual thinking and calculating the contents of mental states.
