The Alienating Mirror: Toward a Hegelian Critique of Lacan on Ego-Formation

This article brings out certain philosophical difficulties in Lacan’s account of the mirror stage, the initial moment of the subject’s development. For Lacan, the “original organization of the forms of the ego” is “precipitated” in an infant’s self-recognition in a mirror image; this event is explicitly prior to any social interactions. A Hegelian objection to the Lacanian account argues that social interaction and recognition of others by infants are necessary prerequisites for infants’ capacity to recognize themselves in a mirror image. Thus mutual recognition with another, rather than self-recognition in a mirror, is what makes possible subsequent ego-formation and self-consciousness. This intersubjective critique suggests that many of the psychoanalytic consequences that Lacan derives from the mirror stage (e.g., alienation, narcissism, and aggressivity) may need to be rethought.

Moral Expertise and the Credentials Problem

Philosophers have harbored doubts about the possibility of moral expertise since Plato. I argue that irrespective of whether moral experts exist, identifying who those experts are is insurmountable because of the credentials problem: Moral experts have no need to seek out others’ moral expertise, but moral non-experts lack sufficient knowledge to determine whether the advice provided by a putative moral expert in response to complex moral situations is correct and hence whether an individual is a bone fide expert. Traditional accounts of moral expertise require that moral experts give reliably correct moral advice supported by adequate justification, an account which, I argue, is too lean in allowing for the possibility of a moral expert who is motivationally indifferent to her own moral judgments and advice. Yet even if the proposition that a moral expert is an individual who provides reliably correct moral advice supported by adequate justification and is necessarily motivated by that advice exhausts the necessary and sufficient conditions for moral expertise, this proposition cannot function as an applicable criterion for non-experts to use in appraising would-be experts’ claims to expertise. The credentials problem thus remains unanswered.

Functional analyses and treatment of precursor behavior

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.     

I like you,I like you not: Understanding the formation of context-dependent automatic attitudes

Previous research has shown that automatic evaluations can be highly context dependent. Expanding on past research demonstrating context effects for existing attitudes toward familiar objects, the present research examined basic principles that guide the formation of context-dependent versus context-independent automatic attitudes. Results from four experiments showed that: (a) newly formed attitudes generalised to novel contexts when prior experiences with the attitude object were evaluatively homogeneous; (b) when prior experiences were evaluatively heterogeneous, automatic evaluations became context sensitive, such that they reflected the contingency between the valence of prior experiences and the context in which these experiences occurred; and (c) when prior experiences were evaluatively heterogeneous across different contexts, novel contexts elicited automatic evaluations that reflected the valence of first experiences with the attitude object. Implications for research on automatic evaluation and attitude change are discussed.     

The effect of object–valence relations on automatic evaluation

Two experiments tested the effect of co-occurrence of a target object with affective stimuli on automatic evaluation of the target when the relation between the target and the affective stimuli suggests that they have opposite valence. Participants learned about targets that ended an unpleasant noise or a pleasant music. The valence of such targets is opposite to the valence of the affective stimuli that co-occur with them. Participants reported preference for targets that ended noise over targets that ended music, but automatic evaluation measures revealed the opposite preference. This suggests that automatic evaluation is sensitive to co-occurrence between stimuli more than to the relation between the stimuli, and that relational information has a stronger influence on deliberate evaluation than on automatic evaluation. These conclusions support the associative-propositional evaluation model (Gawronski & Bodenhausen, 2006), and add evidence regarding the sensitivity of the evaluative-conditioning effect to relational information.     

Enhanced Cognitive Behavior Therapy: A Single Treatment for All Eating Disorders

Eating disorders are serious mental illnesses affecting a significant proportion of women and a smaller number of men. Approximately half of those with an eating disorder (ED) will not meet the criteria for anorexia or bulimia nervosa, and will be diagnosed with an eating disorder not otherwise specified (EDNOS). Until recently, there were no recommended treatments for EDNOS. This article provides an overview of enhanced cognitive behavior therapy, a validated treatment for all forms of EDs.     

Continuous and discrete latent structure models for item response data

Relations are examined between latent trait and latent class models for item response data. Conditions are given for the two-latent class and two-parameter normal ogive models to agree, and relations between their item parameters are presented. Generalizationss are then made to continuous models with more than one latent trait and discrete models with more than two latent classes, and methods are presented for relating latent class models to factor models for dichotomized variables. Results are illustrated using data from the Law School Admission Test, previously analyzed by several authors.     

组织中员工的自愿性工作行为

自愿性工作行为是角色规范之外的自发性行为, 它包括两大类型：一是以组织公民行为、建言行为、周边绩效等为代表的角色外行为; 二是以反生产行为、沉默行为、越轨行为等为代表的负面组织行为。自愿性工作行为的产生是个体与情境相互作用的结果。“组织公民行为-反生产行为”与“建言-沉默”之间的关系并非对立相反, 在一定条件下且可以互相转化, 本研究将特定类目的转化过程推论至总体, 并用情感事件理论、道德补偿原理及经济理性分析对该推论进行理论论证。     

班级集体效能对初中生学业自我效能与学习倦怠的调节作用

采用学习倦怠、学业自我效能、班级集体效能问卷,选取26个班级的1125名初中生作为被试,运用多层线性模型探讨班级集体效能对学业自我效能与学习倦怠的影响。在控制性别和年级的影响后,结果发现:(1)班级集体效能与学习倦怠具有直接的关联:班级正向联合力越高,则学生的学习成就感越高;班级负向联合力越高,则学生的情绪与生理的消耗越严重;班级优秀成员的效能越高,则其他学生学习的成就感越低,师生关系越疏远、生理消耗越严重;而班级成员的自我效能越高,学生的学习成就感越高、情绪的损耗越小;(2)班级集体效能对学业自我效能与学习倦怠之间的关系具有显著的调节作用:班级的正向和负向联合力越强,则学业自我效能对师生疏离的负向影响就越弱;班级的负向联合力越强,则学业自我效能对情绪耗竭的负向影响就越小;优秀成员效能越高,则学业自我效能对学习低成就感的负向影响就越大;而成员自我效能强,则学业自我效能对师生疏离的负向影响也强。
