Costs and Benefits in Item-Method Directed Forgetting: Differential Effects of Encoding and Retrieval

This study examined how encoding and retrieval factors affected directed forgetting costs and benefits in an item-method procedure. Experiment 1 used a typical item-method procedure and revealed a levels-of-processing effect in overall recall. However, the deep encoding condition showed a smaller directed forgetting effect than the shallow encoding conditions. More importantly, “remember” (R) words were selectively rehearsed as indicated by greater recall from the primacy portion of the list and more apt to be recalled before “forget” (F) words. Experiment 2 showed that a deep encoding operation reduced directed forgetting costs and that directed forgetting benefits occurred only when R words were recalled before F words. These findings supported the hypotheses that encoding manipulation affected directed forgetting costs and that directed forgetting benefits were associated with output order bias. Results were discussed in terms of mechanisms that produce item-method directed forgetting.     

Effects of visual focus and gait speed on walking balance in the frontal plane

We investigated how head position and gait speed influenced frontal plane balance responses to external perturbations during gait. Thirteen healthy participants walked on a treadmill at three different gait speeds. Visual conditions included either focus downward on lower extremities and walking surface only or focus forward on a stationary scene with horizontal and vertical lines. The treadmill was positioned on a platform that was stationary (non-perturbed) or moving in a pattern that appeared random to the subjects (perturbed). In non-perturbed walking, medial–lateral upper body motion was very similar between visual conditions. However, in perturbed walking, there was significantly less body motion when focus was on the stationary visual scene, suggesting visual feedback of stationary vertical and horizontal cues are particularly important when balance is challenged. Sensitivity of body motion to perturbations was significantly decreased by increasing gait speed, suggesting that faster walking was less sensitive to frontal plane perturbations. Finally, our use of external perturbations supported the idea that certain differences in balance control mechanisms can only be detected in more challenging situations, which is an important consideration for approaches to investigating sensory contribution to balance during gait.     

My Recency,Our Primacy: How Social Connection Influences Evaluations of Sequences

Individuals have many life experiences (e.g., work and vacations) that consist of a series of interconnected episodes (i.e., temporal sequences). Assessments of such experiences are integral to daily life in that they facilitate future planning and behaviors for individuals. Therefore, these experiences often culminate in evaluations of their global affect. Past work has shown that retrospective, affective evaluations of these sequences generally exhibit an “end effect,” whereby a sequence's end intensity—but not its start intensity—is disproportionately weighted. Yet, researchers have largely investigated experiences that occur alone. In contrast, many real‐world experiences vary in their extent of social connection to others (e.g., working in an office with others versus alone in a cubicle). The present work fills this gap by showing the moderating role of social connection on how episodes are weighted in global affective ratings. Five studies involving two autobiographical experiences spanning several days each (workweek and spring break) and two brief simulated experiences show that high social connection leads to greater (lesser) weighting of the first (last) episode. To our knowledge, we are the first to demonstrate that these effects persist across different forms of social connection (i.e., interpersonal interaction versus semantic priming tasks) and are supported regardless of whether social connection occurs at encoding or retrieval of an experience.

词边界信息对读者阅读歧义短语时眼跳策略的影响

采用Eye Link 2000眼动仪,选取60个歧义短语,要求大学生被试阅读包含有歧义短语的句子。句子的呈现设置了四种条件:正常无阴影、词间阴影、歧义阴影和字间阴影,以探讨词边界信息是否影响读者阅读歧义短语时的注视位置效应。结果发现:读者对歧义短语的首次注视位置在四种条件下基本一致;词边界信息影响读者对歧义短语的再注视概率。结果表明,词边界信息对歧义短语的影响主要体现在眼跳行动(即"where")的晚期阶段。     

The relationships between stressful life events during childhood and differentiation of self and intergenerational triangulation in adulthood

This study examined the relationships between stressful life events in childhood and differentiation of self and intergenerational triangulation in adulthood. The sample included 217 students (173 females and 44 males) from a college in northern Israel. Participants completed the Hebrew versions of Life Events Checklist (LEC), Differentiation of Self Inventory‐Revised (DSI‐R) and intergenerational triangulation (INTRI). The main findings were that levels of stressful life events during childhood and adolescence among both genders were positively correlated with the levels of fusion with others and intergenerational triangulation. The levels of positive life events were negatively related to levels of emotional reactivity, emotional cut‐off and intergenerational triangulation. Levels of stressful life events in females were positively correlated with emotional reactivity. Intergenerational triangulation was correlated with emotional reactivity, emotional cut‐off, fusion with others and I‐position. Findings suggest that families that experience higher levels of stressful life events may be at risk for higher levels of intergenerational triangulation and lower levels of differentiation of self.     

The impact of object carriage on independent locomotion

The current study examined whether carrying objects in one's hands influenced different parameters associated with independent locomotion. Specifically, 14- and 24-month-olds walked in a straight path under four conditions of object carriage – no object (control), one object carried in one hand (one object-one hand), two objects carried in each of the hands (two objects-two hands), and one object carried in both hands simultaneously (one object-two hands). Although carrying objects failed to influence a variety of kinematic parameters of gait, it did affect children's arm postures, with children adopting less mature arm positions when carrying objects. Finally, arm position was related to walking skill, but only for older children when they were not carrying objects. These findings indicate that although a relation does exist between arm positions and gait parameters, this relation is easily disrupted by carrying loads, even small ones.     

Psychosomatic breast and alexithymic breast: A Bionian psychosomatic perspective

The author develops the concept of ‘psychosomatic breast’ in both clinical and theoretical terms, a concept developed by Bion (1962b) to account for a breast in charge of primary symbolization and of the psychosomatic integration of the infant's raw physiological, emotional and sensory experiences. As such, the psychosomatic breast is a prototype, a core in the mother endowed with the capacity for reverie insofar as the transformative function of the latter not only pertains to the primary symbolization of emotional life, but also to its secondary symbolization. The author contends that a primal failure in the transformation of such raw emotional and sensory experiences through the reverie of primary objects results in the incorporation of an ‘alexithymic breast’ – a kind of obstructive object that has become impervious to communication via projective identification and has been internalized as a source of psychic and physical breakdown. This early deficiency in parental reverie is experienced by the infant as a primitive disaster that establishes a point of fixation, a fault line in psychosomatic organization which the individual is likely to regress to, at a later stage, by developing physical illness. The author illustrates the dynamics and the economy of the conflict between psychosomatic and alexithymic breasts thanks to fragments from the analysis of a woman who developed cancer in the course of her psychoanalysis and was eventually cured.     

Concurrent cognitive processes in rat serial pattern learning: II. Discrimination learning,rule learning,chunk length,and multiple‐item memories

The current experiment examined the factors that determine acquisition for elements of highly structured serial patterns. Three groups of rats were trained on three patterns with parallel rule‐based hierarchical structure, but with 3‐, 4‐, or 5‐element chunks, each with a final violation element. Once rats mastered their patterns, probe patterns were introduced to answer several questions. To assess the extent to which the learned response pattern depended on intrachamber location cues for anticipating different element types, Spatial Shift Probes shifted the starting lever of patterns to locations that positioned chunk boundaries where they had never been experienced during training. To assess the extent to which a phrasing cue is necessary for rats to perform a chunk‐boundary response, a Cue Removal Probe tested whether rats would produce a chunk‐boundary response in the correct serial position if the phrasing cue was omitted. To assess the extent to which cues from multiple trials leading up to the violation element are required to anticipate the violation element, Multiple‐Item Memory Probes required rats to make an unexpected response on one of the elements in the last two chunks of the pattern prior to the violation element. The results indicated that rats used multiple concurrent learning and memory processes to master serial patterns, including discrimination learning, rule learning, encoding of chunk length, and multiple‐item memories.     

The location of the Trait Emotional Intelligence in the Zuckerman's Personality Model space and the role of General Intelligence and social status

The aim of this study was to investigate the relationships between Emotional Intelligence (EI) measured by the Trait Emotional Intelligence Questionnaire (TEIQue) and personality measured by the Zuckerman‐Kuhlman‐Aluja Personality Questionnaire (ZKA‐PQ) with the purpose of analyzing similarities and differences of both psychological constructs. Additionally, we studied the relationship among EI, personality, General Intelligence (GI) and a social position index (SPI). Results showed that the ZKA‐PQ predicts the 66% (facets) and the 64% (factors) of the TEIQue. High scores in EI correlated negatively with Neuroticism (r: –0.66) and Aggressiveness (r: –0.27); and positively with Extraversion (r: 0.62). Oblique factorial analyses demonstrated that TEIQue scales were located basically in the Neuroticism and Extraversion factors. The SPI and GI no loaded in any factor. These findings showed that EI is a not a distinct construct of personality and it cannot be isolated in the ZKA‐PQ personality space. GI is related with the SPI (r: 0.26), and EI correlated with GI (r: 0.18) and SPI (r: 0.16). Nevertheless, we found differences between GI high groups and the TEIQue and ZKA‐PQ factors when controlling age and sex. These findings are discussed in the individual differences context.
