Imperfection,Indecision, and Hoarding

Hoarding disorder is a new DSM-5 disorder that causes functional impairment and affects 2 to 6% of the population (Frost and Steketee 2014). The current study evaluated a multiple mediation model with 243 undergraduate women in which indecisiveness (VOCI; Thordarson et al. Behaviour Research and Therapy, 42(11), 1289-1314, 2004) and decisional procrastination (DPS; Mann 1982) mediated the relationship between dimensions of perfectionism (F-MPS-B; Burgess et al. 2016a) and hoarding behavior (SI-R; Frost et al. Behaviour Research And Therapy, 42(10), 1163–1182, 2004) and excessive acquiring (CAS; Frost et al. Annual Review of Clinical Psychology, 8, 219–242, 2012). Multiple mediational analyses indicated a significant indirect effect for decisional procrastination, but not indecisiveness, in mediating evaluative concerns (but not striving) to SI-R Total, SI-R Clutter, SIR Excessive Acquisition, and both CAS subscales. Both mediators were significant pathways between evaluative concerns and SI-R Difficulty Discarding. These findings support a cognitive behavioral model of hoarding, suggesting that evaluative concerns produces problems in decision-making that influence acquisition, discarding, and clutter.     

A metaphysics for practical knowledge

Is Anscombean practical knowledge independent of what the agent actually does on an occasion? Failure to understand Anscombe’s answer to this question is a major obstacle to appreciating the subtlety and plausibility of her view. I argue that Anscombe’s answer is negative, and turns on the nature of mistakes in performance, and reveals a distinctive implicit metaphysics of mind and knowledge, structured by related capacities and exercises of capacities. If my interpretation is correct, then practical knowledge shares features with knowledge-how and knowledge-that, but deserves its own epistemic category.     

A Study of Black and White College Women

In an examination of career aspirations, 101 black and 530 white college women were asked to indicate their occupational and educational plans, important considerations for career choices, and their attitudes toward combining the roles of career and family. Results indicated that women who planned careers in male-dominated occupations had higher career and educational aspirations than women who desired careers in femaledominated occupations. Black women who planned careers in male-dominated professions showed high levels of aspirations, planned more education than was necessary for the desired occupations, and perceived less conflict in combining the roles of career and family than their white counterparts. There were few differences between black and white women in their attitudes toward the traditional roles of men and women. Those choosing female-dominated careers, however, had more traditional attitudes regardless of race. Implications of these findings for the influence of occupational gender dominance on career aspirations are discussed.

Linear vection in the central visual field facilitated by kinetic depth cues.

Illusory self-motion (vection) is thought to be determined by motion in the peripheral visual field, whereas stimulation of more central retinal areas results in object-motion perception. Recent data suggest that vection can be produced by stimulation of the central visual field provided it is configured as a more distant surface. In this study vection strength (tracking speed, onset latency, and the percentage of trials where vection was experienced) and the direction of self-motion produced by displays moving in the central visual field were investigated. Apparent depth, introduced by using kinetic occlusion information, influenced vection strength. Central displays perceived to be in the background elicited stronger vection than identical displays appearing in the foreground. Further, increasing the eccentricity of these displays from the central retina diminished vection strength. If the central and peripheral displays were moved in opposite directions, vection strength was unaffected, and the direction of vection was determined by motion of the central display on almost half of the trials when the centre was far. Near centres produced fewer centre-consistent responses. A complete understanding of linear vection requires that factors such as display size, retinal locus, and apparent depth plane are considered.     

Phonological ambiguity and lexical ambiguity: effects on visual and auditory word recognition

Three experiments in Serbo-Croatian were conducted on the effects of phonological ambiguity and lexical ambiguity on printed word recognition. Subjects decided rapidly if a printed and a spoken word matched or not. Printed words were either phonologically ambiguous (two possible pronunciations) or unambiguous. If phonologically ambiguous, either both pronunciations were real words or only one was, the other being a nonword. Spoken words were necessarily unambiguous. Half the spoken words were auditorily degraded. In addition, the relative onsets of speech and print were varied. Speed of matching print to speech was slowed by phonological ambiguity, and the effect was amplified when the stimulus was also lexically ambiguous. Auditory degradation did not interact with print ambiguity, suggesting that perception of the spoken word was independent of the printed word.
