Affective evidence that inhibition is involved in separating accessory representations from active representations in visual working memory

ABSTRACT

The multiple state theory of working memory suggests that representations are divided into two states: focused-on active representations and accessory memories held for later use. Here we tested two competing hypotheses regarding the neurocognitive mechanisms responsible for this separation: (1) that accessory memories undergo inhibition or (2) that accessory memories are amplified less than active representations. We explored whether accessory memories undergo affective devaluation, a known index of the involvement of inhibition in a visual task. On each trial participants memorized four items, were cued to focus on one, and then completed a visual search or an affective evaluation task. While search distractors matching the colour of an active item slowed search, those matching an accessory memory did not, replicating previous findings that only active items guide search. Also, accessory items were affectively devalued compared to baseline and active items, supporting the hypothesis that accessory memories undergo inhibition.     

Establishing a relational field that fosters learning processes: Some tentative propositions derived from trainee experiences

In this article, we look at the recent introduction of more relational-oriented learning principles and how they translate into practice by documenting the experiences of both trainees and instructors. It became clear that actors held different opinions and viewpoints on learning objectives and process ingredients for achieving these objectives. This divergence in opinions resulted in an “impoverished” learning trajectory. We suggest that remedying this situation implies introducing reflexivity regarding learning processes or, stated otherwise, addressing “meta-cognitions” that participants inevitably bring to the process as they affect the way in which people engage in the relational field that encompasses the learning trajectory. Despite some recent arguments in favour of a distinction between cognitive and meta-cognitive mediation, we argue for a similar approach with respect to both types of mediation. We end this article by suggesting that designing learning trajectories with this dual concern in mind might open the road to “learning to learn”.     

Shifts in Perceived Job Content during Early Employment

Abstract

This paper focuses on shifts in perceived job content among two occupational panels (office technology workers and machine operators) during the first year of their professional career. A shortened version of Fine's Functional Job Analysis is used to measure perceived job content, and at each of the two time stages (i.e. stage T1 and stage T2) the data related to the three domains of People, Things, and Data are optimally scaled and then recoded to a categorical indicator of job content complexity. Shifts in perceived job content are studied by application of log-linear analysis to the multidimensional contingency table obtained by the cross-tabulation of the T1 and the T2 data. The results indicate that there is no general progress or decline in job content activities over time, except for the Things domain. The findings also suggest that there is a substantial symmetry between job progression and degression, and that the bulk of content switches is to adjacent levels of complexity.     

When authorities influence followers' affect: The interactive effect of procedural justice and transformational leadership

The present research examined the effect of procedural justice and transformational leadership style on followers' affective responses: Self-esteem and emotions. It was predicted that procedural justice would positively influence both followers' self-esteem and emotions, but particularly so if the leader displayed a transformational style. Results from a scenario experiment, a laboratory experiment, and an organizational survey indeed showed that procedural justice and transformational leadership style interacted to influence followers' self-esteem and emotions, such that the positive relationships between procedural justice and the affective measures were more pronounced when the leadership style was high in transformational behaviour. Implications in terms of integrating the leadership and procedural justice literatures are discussed.     

The four faces of omission

In this paper, the ontological, terminological, epistemological, and ethical aspects of omission are considered in a coherent and balanced framework, based on the idea that there are omissions which are actions and omissions which are non-actions. In particular, we suggest that the approach to causation which best deals with omission is Mackie's INUS conditional proposal. We argue that omissions are determined partly by the ontological conditional structure of reality, and partly by the interests, beliefs, and values of observers. The final upshot is that moral judgments involved in cases of omissions cannot be grounded on, but are the ground for judgments about what INUS conditions count as omissions.     

Misers or lovers? How a reflection on Christian mysticism caused a shift in Jacques Lacan’s object theory

In his sixth seminar, Desire and Its Interpretation (1956–1957), Lacan patiently elaborates his theory of the ‘phantasm’ ($?a), in which the object of desire (object small a) is ascribed a constitutive role in the architecture of the libidinal subject. In that seminar, Lacan shows his fascination for an aphorism of the twentieth century Christian mystic Simone Weil in her assertion: “to ascertain exactly what the miser whose treasure was stolen lost: thus we would learn much.” This is why, in his theory, Lacan conceptualizes the object of desire as the unconsumed treasure—and, in that sense, the “nothing”—on which the miser’s desire is focused. But the more Lacan develops his new object theory, the more he realizes how close it is to Christian mysticism in locating the ultimate object of desire in God, in a sevenfold “nothing” (to quote the famous last step in the ascent of the Mount Carmel as described by John of the Cross). An analysis of Shakespeare’s Hamlet allows Lacan to escape the Christian logic and to rearticulate the object of desire in an ‘unchristian’ tragic grammar. When he replaces the miser by the lover as paradigm of the subject’s relation to its object of desire, he substitutes a strictly Greek kind of love—eros, not agape—for the miser’s relationship to his treasure. Even when, in the late Lacan, “love” becomes a proper concept, its structure remains deeply “tragic.”     

重组人粒细胞集落刺激因子预防肿瘤化疗后Ⅲ度以上骨髓抑制的疗效分析

探讨重组人粒细胞集落刺激因子(rhG-CSF)对初诊晚期肿瘤患者化疗后骨髓抑制的合理预防用药时机.采用前瞻性随机方法,筛选首次化疗后出现Ⅲ度～Ⅳ度骨髓抑制的肿瘤患者,以化疗前24h内给予rhG-CSF的为预防治疗组;以化疗前未预防性给药为对照组,采用组间对照法,比较两组化疗后骨髓抑制的发生情况.结果发现两组的骨髓抑制发生率,预防组明显低于对照组,且Ⅲ度以上骨髓抑制发生率也明显降低.首次化疗后出现Ⅲ度～Ⅳ度骨髓抑制的肿瘤患者,下次化疗前24h内预防性给予rhG-CSF,能有效控制肿瘤化疗后骨髓抑制的发生,降低感染的风险,值得推广.     

Leader endorsement in social dilemmas: Comparing the instrumental and relational perspectives

This chapter examines the role of leadership in overcoming social dilemmas within groups. First, based on prior theorising and research we present two alternative perspectives on leader endorsement in social dilemmas, an instrumental and a relational perspective. Next, we systematically compare these perspectives in a series of experiments investigating leadership in social dilemmas created within small groups in the laboratory. The results of our studies suggest that when their personal identity is salient, group members more strongly endorse leaders who are perceived to be instrumental in solving the freerider problem. In contrast, when a social identity is salient, members more strongly endorse leaders who fulfil their relational needs. Based on these findings we propose a differential needs model of leader endorsement in social dilemmas.     

A functional-cognitive framework for attitude research

In attitude research, behaviours are often used as proxies for attitudes and attitudinal processes. This practice is problematic because it conflates the behaviours that need to be explained (explanandum) with the mental constructs that are used to explain these behaviours (explanans). In the current chapter we propose a meta-theoretical framework that resolves this problem by distinguishing between two levels of analysis. According to the proposed framework, attitude research can be conceptualised as the scientific study of evaluation. Evaluation is defined not in terms of mental constructs but in terms of elements in the environment, more specifically, as the effect of stimuli on evaluative responses. From this perspective, attitude research provides answers to two questions: (1) Which elements in the environment moderate evaluation? (2) What mental processes and representations mediate evaluation? Research on the first question provides explanations of evaluative responses in terms of elements in the environment (functional level of analysis); research on the second question offers explanations of evaluation in terms of mental processes and representations (cognitive level of analysis). These two levels of analysis are mutually supportive, in that better explanations at one level lead to better explanations at the other level. However, their mutually supportive relation requires a clear distinction between the concepts of their explanans and explanandum, which are conflated if behaviours are treated as proxies for mental constructs. The value of this functional-cognitive framework is illustrated by applying it to four central questions of attitude research.     

The Relationship Between Personality,Burnout, and Engagement Among the Indian Clergy

This study examined the relationship between the Big Five personality dimensions, burnout, and engagement among 511 Indian Catholic diocesan priests. We expected that Neuroticism would be positively associated with burnout and negatively associated with engagement. Moreover, we expected Extraversion, Openness, Agreeableness, and Conscientiousness to be negatively associated with burnout and positively associated with engagement. Hierarchical regression analyses largely confirmed these expectations. Results are discussed in the context of the broader literature on burnout and engagement, as well as the literature on priesthood.
