Minor Variations in Maze Patterns: II. The Effect upon the Accuracy of the Reproductions of the Maze

After an exam in which the order of question presentation was varied on the basis of pre-established difficulty levels, student perceptions of the test, course, and instructor were compared. Perceptual scores for 68 Ss across nine evaluative factors were analyzed. The hypothesized existence of a primacy/recency halo effect on perceptual bias received partial support. Five of nine factors were significant in the hypothesized direction at the .05 level.     

Temporal Finitude and Finitude of Possibility: The Double Meaning of Death in Being and Time

Abstract

The confusion surrounding Heidegger’s account of death in Being and Time has led to severe criticisms, some of which dismiss his analysis as incoherent and obtuse. I argue that Heidegger’s critics err by equating Heidegger’s concept of death with our ordinary concept. As I show, Heidegger’s concept of death is not the same as the ordinary meaning of the term, namely, the event that ends life. But nor does this concept merely denote the finitude of Dasein’s possibilities or the groundlessness of existence, as William Blattner and Hubert Dreyfus have suggested. Rather, I argue, the concept of death has to be understood both as temporal finitude and as finitude of possibility. I show how this reading addresses the criticisms directed at Heidegger’s death analysis as well as solving textual problems generated by more limited interpretations of the concept.     

Sex differences in a human analogue of the Radial Arm Maze: the "17-Box Maze Test"

This study investigated sex differences in spatial memory using a human analogue of the Radial Arm Maze: a revision on the Nine Box Maze originally developed by called the 17-Box Maze Test herein. The task encourages allocentric spatial processing, dissociates object from spatial memory, and incorporates a within-participants design to provide measures of location and object, working and reference memory. Healthy adult males and females (26 per group) were administered the 17-Box Maze Test, as well as mental rotation and a verbal IQ test. Females made significantly fewer errors on this task than males. However, post hoc analysis revealed that the significant sex difference was specific to object, rather than location, memory measures. These were medium to large effect sizes. The findings raise the issue of task- and component-specific sexual dimorphism in cognitive mapping.     

Temporal Relations in Daily-Reported Maternal Mood and Disruptive Child Behavior

Examined temporal relations between maternal mood and disruptive child behaviour using daily assessments of 30 mother-child dyads carried out over 8 consecutive weeks (623 pooled observations). Pooled time-series analyses showed synchronous fluctuation in child behaviour and maternal distress. Time-lagged models showed temporal relations between maternal and child outcomes that changed according to the type of maternal mood and child behaviour being reported. Controlling for cross-sectional relations, maternal anger and fatigue were related to previous child inattentive/impulsive/overactive behaviour (IO) and maternal confusion related to previous child oppositional/defiant behaviour (OD). However, maternal depression, low vigour, anger, and anxiety each predicted subsequent child IO and maternal confusion and anxiety each predicted subsequent child OD. Mutual influences on maternal and child functioning were interpreted in the context of interpersonal mechanisms that mediate psychological problems within families and their implications for treatment.     

The Wall-Seeking Tendency and Maze Learning in the White Rat

A partial replication and extension of the semantic differential was used to test the effects of modified middle interval instructions on rotated factor loadings derived from Ss' responses. The partial replication is in good agreement with the findings published by Osgood et al. (5). However, the results from Ss responding to the modified middle interval instructions differ markedly from those in published and control conditions, yielding an interpretable fourth factor suggesting the achievement of more subtle nuance of meaning.
