Effects of attention on localization of stimuli in the visual field

Subjects localized a small letter that appeared inside one of three large circles that was either validly or invalidly cued. The results indicated that, although unattended stimuli were localized fairly accurately, attention still improved localization. Moreover, the results revealed a greater dispersion of localization responses along the horizontal axis and also showed that mislocalization of attended peripheral stimuli is biased toward the periphery.     

Sources of self-identity among Turkish adolescents

As part of the International Self-Identity Research Project, this study explored sources of identity among Turkish adolescents. The interview sample consisted of three male and three female high school students in Ankara, Turkey. The results indicated that social, familial, personal, physical, and moral-ethical dimensions contributed to adolescents' definitions of self, but to different degrees. Social and familial dimensions were very influential and were used as reference points for defining self in other areas. Physical and personal aspects of identity were also apparent, but were not as salient as social and familial dimensions. Patriotism and religion played a role in moral-ethical identity. Overall, self-identity influenced emotional state, cognitive and behavioral functioning, and social relations to a significant degree.     

味觉厌恶性条件反射与条件反射性免疫抑制的研究

以环磷酰胺的注射为非条件刺激（ＵＣＳ）,糖精水的摄入为条件刺激（ＣＳ）,并以血白细胞和淋巴细胞数量及脾淋巴细胞的转化反应为免疫指标,糖精水的饮用量为行为指标,通过改变条件刺激与非条件刺激结合的次数来观察条件反射性厌恶行为与条件反射性免疫抑制的反应。结果表明不管是一次性的还是两次性的ＣＳ－ＵＣＳ结合训练都能使动物明显地建立起味觉厌恶性条件反射,然而条件反射性免疫抑制只在两次性ＣＳ－ＵＣＳ结合训练后才     

Reasoning ability in older adults measured through letter and number series

Letter series and number series tests, consisting of items based on identical rules, were administered in a counterbalanced design to 58 persons (46 women and 12 men) between the ages of 61 and 88 years to determine their relative efficacy (relative difficulty and acceptability) as measures of inductive/deductive reasoning ability. Results indicated that letter and number series tests, in which each item in one has a same-rule counterpart in the other, were not equivalent in regard to their relative difficulty or popularity among the elderly. The number series test was significantly (p 0001) easier and more popular than its letter series counterpart. Some of the implications of these findings for assessing reasoning ability in the elderly were specified.

Effects of Self-Monitoring on On-Task Behaviors of At-Risk Middle School Students

The purposes of this study were to evaluate the effects of self-monitoring on increasing the on-task behaviors of four at-risk middle school students, and to examine its indirect effects on academic performance. Additionally, we attempted to develop and validate cost- and time-efficient procedures that typical classroom teachers could use. The data from a multiple baseline design across three academic settings, replicated with four students, revealed immediate increases in on-task behavior as each student began to self-monitor in each sequential setting. The data also revealed slightly higher levels of academic performance and, in most instances, gradually accelerating trends. These findings suggest that self-monitoring is a cost- and time-efficient procedure that classroom teachers can use to teach at-risk students to manage their own behaviors.     

On the cognitive processes underlying contextual interference and observational learning

The main goal of the present study was to determine whether observation of an unskilled model learning a timing task enables the observer to develop a cognitive representation of the task similar to the one acquired through physical practice (Adams, 1986; Bandura, 1977; Lee & White, 1990). To reach that goal, we tested whether a contextual interference effect would be obtained in a retention test of subjects who had observed an individual practicing three variations of a timing task under a random or a blocked schedule of practice. Similar patterns of results in an immediate retention test were found following observation and physical practice. This suggests that observation indeed engaged the observers in the same type of cognitive activities as did physical practice. Moreover, a schedule of practice made up of 100% physical practice led to improved learning compared with a schedule of practice made up of 50% observation followed by 50% physical practice. This suggests that learning is enhanced more by numerous implementations of a motor program than by its mere construction or retrieval.     

Stimulus congruity,irrelevant spatial SR correspondence,and display-control arrangement correspondence: A reply to O'Leary,Barber, and Simon (1994)

Summary We recall how Hasbroucq and Guiard (1991) defined stimulus (S) congruity, the SS-correspondence factor they demonstrated to account for both the Simon effect and the Hedge and Marsh effect, and how they explained the mechanisms that bring S congruity into play in the verbal and nonverbal versions of the Simon task and in the Hedge and Marsh task. We show that, contrary to O'Leary, Barber, and Simon's claim, Hasbroucq and Guiard used a consistent definition of S congruity across the various tasks of interest. Finally, we recognize that Hasbroucq and Guiard's experiments produced no direct falsification of the display control arrangement correspondence (DCC) hypothesis — the special-purpose hypothesis put forward by Simon and his group as an attempt to reconcile the Hedge and Marsh effect with their interpretation of the Simon effect in terms of irrelevant spatial SR correspondence —, but we argue that the DCC account is unnecessary and implausible.
