Eye movements during the reading of compound words and the influence of lexeme meaning

We examined the use of lexeme meaning during the processing of spatially unified bilexemic compound words by manipulating both the location and the word frequency of the lexeme that primarily defined the meaning of a compound (i.e., the dominant lexeme). The semantically dominant and nondominant lexemes occupied either the beginning or the ending compound word location, and the beginning and ending lexemes could be either high- or low-frequency words. Three tasks were used--lexical decision, naming, and sentence reading--all of which focused on the effects of lexeme frequency as a function of lexeme dominance. The results revealed a larger word frequency effect for the dominant lexeme in all three tasks. Eye movements during sentence reading further revealed larger word frequency effects for the dominant lexeme via several oculomotor motor measures, including the duration of the first fixation on a compound word. These findings favor theoretical conceptions in which the use of lexeme meaning is an integral part of the compound recognition process.     

生命伦理学:权力与不公正--在第六届国际生命伦理学大会的致辞

在现代生命伦理学的讨论中,主要关注的是改造医患关系中的权力关系。通过强调人权和对个人尊严的尊重,对脆弱人群授予权利已经达到。然而,在卫生保健中,权力的不平衡依然普遍存在。这在相当程度上与对社会不公正的关注不够有关。那种权力的不平衡加之新的权力形式的发展,例如,通过新的遗传生物技术,产生了对日益增长的社会不公的恐惧与忧虑。由此,扩展与公共卫生有关的伦理学讨论将受到关注。政治哲学研究也需要变为改造国际权力关系和改善人口健康。     

Intimacy and the magnitude and experience of episodic relational uncertainty within romantic relationships

This paper seeks to clarify the association between the intimacy and the magnitude of relational uncertainty generated by specific events within romantic relationships. More specifically, we suggest that episodic relational uncertainty peaks at moderate levels of intimacy. We conducted a cross–sectional study in which 328 romantic relationship participants reported their reactions to a hypothetical relational uncertainty increasing event. Although the effect size was small, findings documented a curvilinear association between intimacy and episodic relational uncertainty. Further, hierarchical regression results supported our predictions about the effects of intimacy and episodic relational uncertainty on people’s reactions to the events. We discuss the implications of our findings for understanding the roles of both intimacy and episodic relational uncertainty within romantic relationships.     

Coherent plaids are preattentively more than the sum of their parts

We investigated whether plaids activate preattentive mechanisms that are distinct from those activated by their component gratings. Observers searched for a target plaid, the sum of two perpendicular components in a circular window (radius = 0.65°). The target was present on half the trials. On all trials, half of the distractors had the same frequency and orientation as one component of the plaid, and the rest were the same as the other component. The target and the distractors were arrayed evenly on a circle (radius = 2.36°) around fixation. Target and distractor contrasts were randomly perturbed up to ±30%. The following results held for each of the 6 participants tested. (1) When F1 = 2 c/deg and F2 = 5.25 c/deg, response times (RTs) increased significantly when set size (number of distractors plus target, if present) was increased from four to eight. (2) When the spatial frequencies of both plaid components were the same (i.e., both 2 c/deg or both 5.25 c/deg), RTs increased very slightly, if at all, when set size was increased from four to eight. These results suggest the existence of a preattentive, plaid-sensitive mechanism with band-limited input that does not respond to individual grating components.     

Positive and negative aspects of sociotropy and autonomy

The predictions of cognitive theory of depression with regard to personality modes have not been consistently supported. One explanation is that theoretical attention has been unduly centered on maladaptive aspects of personality. The content validity of the Sociotropy-Autonomy Scale (SAS) was explored with regard to the external correlates of positively and negatively self-evaluative items. One hundred twenty-four undergraduates completed the SAS and several criterion measures. Positively and negatively toned SAS items exhibited different external correlates, with only negatively toned items being associated with symptom and negative cognition measures. Moreover, the pattern of mood correlates reported by Clark and Beck (1991) for three subscales of a revised SAS Autonomy scale corresponded to the valence of each subscale's items, as determined by content analysis. Whereas sociotropy and autonomy are conceptually defined in terms of placing a high value on certain goals or experiences, the SAS may be overbalanced by expressions of self-criticism or insecurity about these values.
