Disorientation inhibits landmark use in 12-18-month-old infants

Recent research has indicated that, particularly under conditions of inertial disorientation, mammals may be sensitive to landmark configuration geometry at the expense of individual featural information when locating hidden goals. The current study sought to establish whether landmark use could be demonstrated in 12-18-month-old infants with and without a disorientation procedure, and with geometrically ambiguous landmark configurations. A peekaboo paradigm was employed in which infants learned to anticipate a peekaboo event after a cue from two locations within a circular arena, followed by a test trial from a novel position in which no peekaboo occurred after the cue. In all conditions, an isosceles triangle arrangement of landmarks was used, with peekaboo occurring between the landmarks of one of the two equal "sides", thus being geometrically ambiguous. In two conditions, the landmarks were distinctive, and in two further conditions, they were identical. In one of the distinctive conditions and one of the identical landmark conditions, infants underwent a disorientation procedure in between training and test trials. Only oriented infants with distinctive landmarks were successful in test trials, thus suggesting that infants are able to use the individual features of landmarks to locate a goal, but can only do so if oriented.     

Personal moral philosophies and moral choice

The moral choices and post-transgression reactions of individuals who adopted varying personal moral philosophies were examined in an experimental setting that permitted the manipulation of the salience of moral norms and the nature of the consequences of one's actions. As predicted, the two situational variables had a strong impact on moral action; only 50.0% of the subjects chose to violate a moral norm when that norm was salient and they would personally benefit by their actions; this percentage increased to 76.2% in the other conditions. Personal ethical philosophies also influenced moral choices and post-transgression reactions, for more of the idealistic subjects chose to act immorally relative to the low idealists (91.66% vs 70.83%), and subjects who were low in both idealism and relativism were less likely to transgress a moral norm if they personally would benefit. The results lend support to the proposed interpersonal model of morality, particularly as applied to post-transgression reactions.     

Fantasy Objects: The Perception of Safety of Emergency Shelter in Place Kits

Using interview data (n = 30) of residents in Calhoun County, Alabama, we examine the meaning respondents give to the objects (shelter-in-place kits) disseminated to residents in order to manage risk of accidents from Anniston Army Depot’s Chemical Weapons storage and incinerator activities. Our research builds on previous research examining how organizations engage in ‘fantasy planning,’ where they create plans that objectively do not increase safety but do create the perception of safety within the organization and especially the public.     

Protective Factors for Deviance: A Comparison of Rural and Urban Youth

Based on data from the 2010, 2012, and 2014 Communities that Care Youth Survey, the authors examine the protective factors associated with rural and urban students in grades 6 through 12 across several domains. This research is based on the literature that associates rural areas with a more protective environment and resulting lower rates of deviance. Findings were mixed, but overall rural youth had higher protective factor scores. A summary of all 84 protective factor scores follows: 26 factors shown no significant different between rural and urban students; on 42 protective factors rural youth had higher scores, as opposed to urban youth with higher protective scores on only 16 factors. Implications of findings for crime and delinquency are discussed.     

Perceptual isolation effects: Short-term visual storage vs cognitive-perceptual structure

Two hypotheses concerning the effects of perceptual isolation were examined. Three experimental groups were defined by the interval between the first and second stimulus presentations within a recognition-discrimination problem. Ninety Ss were exposed to 12 recognition-discrimination problems for each of three physical dimensions of random forms, both before and after 1/2 h of perceptual isolation. Analyses of the number of correct responses indicated support for the hypothesis that isolation increases the duration of the short-term visual storage, but not for the hypothesis that isolation produces change in the hierarchy of physical dimensions to which Ss selectively attend.     

An individual differences analysis of interdimensional additivity in multidimensional scaling

Comparative judgments of the dissimilarity between schematic faces varying on 1, 4, 7, or 10 binary attributes were obtained under two instructional sets. Using the Tucker-Messick procedure, three subgroups of like-perceiving Ss were isolated and the nature of cue-utilization by each described. Perceptual independence of attributes was demonstrated both within and between instructional sets for Subgroups 1 and within instructional sets for Subgroup 2. The Subgroup 3 results indicated an interaction of the attributes. Data from the Shot cognitive elements test differentially characterized Subgroups 1 and 2, but did not uniquely characterize Ss requiring more complex models for the combination of attributes. The study illustrates the possible usefulness of an individual differences approach to the study of selective attention and information processing.
