Infants' understanding of occlusion of others' line-of-sight: Implications for an emerging theory of mind

Infants' gaze following provides information about their understanding of others' perception and attention. Gaze following when the other looks in the presence (and absence) of visual obstacles can be especially informative. In the present study the gaze-following behaviour of 14- and 18-month-old infants was examined in opaque barrier, clear barrier, and non-barrier situations in order to investigate whether infants at this age understand the referential nature of looking. A hypothesis positing that infants grasp the referential nature of gaze would predict that infants would not follow gaze when the looker's gaze is blocked (as in an opaque barrier situation), but would follow gaze in both non-barrier and clear barrier situations. This hypothesis was contrasted with two other “leaner” interpretations predicting contrasting patterns of looking in the same situations. Results showed that both 18- and 14-month-old infants followed gaze as predicted by the richer, referential account.     

Long-term effect of theory of mind on school achievement: The role of sensitivity to criticism

This study adds to the research on theory of mind (ToM) and school achievement by testing whether the mediating effect of sensitivity to criticism is significant when considered longitudinally and using an index of academic performance that incorporates both direct and indirect measures. A group of 49 children was tested during the last year of kindergarten (Time 1, mean age = 5 years and 6 months), in Year 1 (Time 2, mean age = 6 years and 5 months) and Year 5 (Time 3, mean age = 10 years and 2 months) of primary school. Children's ToM and verbal ability were tested at each time point, sensitivity to criticism at Time 2 and school achievement at Time 3. Results showed that sensitivity to criticism (as indexed by self-reported ability rating) mediates the relationship between Time 1 ToM and Time 3 school achievement. Practical implications of this pattern of associations are discussed.     

The role of attention during retrieval in working-memory span: A dual-task study

We tested the hypothesis that retrieving target words in operation span (OSpan) involves attention-demanding processes. Participants completed the standard OSpan task and a modified version in which all equations preceded all target words. Recall took place under either full attention or easy versus hard divided-attention conditions. Recall suffered under divided attention with the recall decrement being greater for the hard secondary task. Moreover, secondary-task performance was disrupted more by the standard OSpan task than by the modified version with the hard secondary task showing the larger decrement. Finally, the time taken to start recalling the first word was considerably longer for the standard version than for the modified version. These results are consistent with the proposal that successful OSpan task performance in part involves the attention-demanding retrieval of targets from long-term memory.     

Adults see vision to be more informative than it is

Humans gain a wide range of knowledge through interacting with the environment. Each aspect of our perceptual experiences offers a unique source of information about the world—colours are seen, sounds heard and textures felt. Understanding how perceptual input provides a basis for knowledge is thus central to understanding one's own and others' epistemic states. Developmental research suggests that 5-year-olds have an immature understanding of knowledge sources and that they overestimate the knowledge to be gained from looking. Without evidence from adults, it is not clear whether the mature reasoning system outgrows this overestimation. The current study is the first to investigate whether an overestimation of the knowledge to be gained from vision occurs in adults. Novel response time paradigms were adapted from developmental studies. In two experiments, participants judged whether an object or feature could be identified by performing a specific action. Adult participants found it disproportionately easy to accept looking as a proposed action when it was informative, and difficult to reject looking when it was not informative. This suggests that adults, like children, overestimate the informativeness of vision. The origin of this overestimation and the implications that the current findings bear on the interpretation of children's overestimation are discussed.     

Theory of mind and epistemological development: the relation between children's second-order false-belief understanding and their ability to reason about evidence

The study investigates the hypothesis that children's ability to attribute second-order beliefs facilitates their understanding of evidence, as seen in the ability to distinguish between causes and reasons. Seventy-four children 5–7 yr old were given belief and evidence tests. The belief tests assessed their ability to represent and reason from second-order false-beliefs, and the evidence tests assessed their ability to distinguish between the cause of a situation and a person's reason for believing it. The relation between performance on the two tests was determined, taking into account general language and non-verbal reasoning abilities. Results show that performance on the belief test and on the evidence part of the evidence test improved significantly over the age range, and that a significant proportion of variance in the evidence test scores is accounted for by second-order false-belief understanding, over and above that accounted for by general language and non-verbal abilities. The argument is made that second-order false-belief understanding is fundamental to children's epistemological development, underlying not just their understanding of evidence, but also their understanding of inference and truth.     

THE THEOLOGICAL ETHICS OF HERBERT McCABE, OP: A REVIEW ESSAY

Herbert Mc Cabe, OP (d. 2001), was a significant theological figure in England in the last century. A scholar of Aquinas, he was also influenced by Wittgenstein and Marx, his reading of whom helped him articulate a distinctive Thomistic account of human embodiment that serves as a critique of other dominant approaches in ethics. This article shows McCabe's contribution to moral theology by placing his work in conversation with other important approaches, namely, situation ethics, proportionalism, and the New Natural Law Theory.     

Driving construals: Personal Construct Theory in a reckless driving context

With research revealing low road safety campaign efficacy and links between reckless driving behaviors and crash frequency, further investigation into the foundations and composition of driver education and training is required. Through two studies, the current research aimed to develop a measure that utilized the principles of Kelly’s (1955) Personal Construct Theory to (a) elicit constructs, or construals, specific to selected elements of reckless driving behaviors, (b) pilot a method in which the elicited constructs could be measured by asking participants to choose those they deemed most important, (c) group participants based on their constructs, and (d) assess between-group differences in self-reported reckless driving behavior. Results suggest that drivers can be categorized based on the constructs they use, and that rates of self-reported past engagement in reckless driving behavior, and willingness to do so in the future, vary systematically between these construal-based driver categories. Continuing research is required to develop and test applications of these findings.     

Approaching the true self: Promotion focus predicts the experience of authenticity

Research on subjective authenticity identifies several psychological antecedents that seem naturally tied to subjectively authentic experiences. Four studies (N = 525) tested the hypothesis that promotion focus (compared to prevention focus) represents another shared antecedent of subjective authenticity. Studies 1 and 2 examined correlations between regulatory focus and subjective authenticity in the context of goal-pursuit and interpersonal interactions. Studies 3 and 4 were within-subjects experiments designed to manipulate regulatory focus and examine the effects of promotion and prevention focus on subjective authenticity. Across all studies, we found that promotion focus (relative to prevention focus) was a robust predictor of subjective authenticity. Implications and future directions are discussed.     

Reaction to Mortality: An Interdisciplinary Organizing Principle for the Human Sciences

Ernest Becker's theory about death denial is one example of depth psychological theory. Because very important features of Becker's theory have now successfully and singularly met the rigorous empirical testing of Terror Management Theory (TMT), it must be concluded that the theory of death denial stands apart from and above alternative depth psychological theories in explaining human behavioral and attitudinal motivation. Nevertheless, TMT only touches the surface of Becker's theory in the round. This essay looks at how Becker's wider theories of death denial are applied to (1) personal psychological, (2) social psychological, (3) political, and (4) spiritual aspects of human experience and suggests that what Becker has given us is an organizing principle, a theory of considerable integrative, explanatory, and interpretive power, for a broadly interdisciplinary social science of human behavior.
