The development of referential offering in the first year

The ontogeny of referential offers was examined in a longitudinal, within dyad case study of two mother–infant pairs. A combination of microanalytic and qualitative methodologies was employed in describing the functions and morphology of this gesture, as well as its temporal and sequential organization with a number of infant and maternal behaviours. Offers were found to emerge from repetitive, exploratory play routines that provide infants with alternative visual perspectives on objects, and were facilitated by mothers' support of infants' immature attentional, motoric and arousal regulation capacities. Offers were observed to co. occur with maternal behaviours that direct and maintain infants' attention to objects. Our observations suggest that offers are transformed through guided interactions into conventional communicative gestures. Offering arises as mothers become part of the infants' exploratory play routines, gradually changing the function of the behaviour of the infants. These observations are consistent with dynamic systems models of development.     

The effect of observer's set on the processing of temporally distributed items1,2

Abstract: Perception of the second of two rapidly presented targets is impaired when the temporal lag between them is short (attentional blink, AB). Previous studies showed two types of AB functions. One is that the performance for the second target has been found to be most impaired at the shortest lag (Lag 1), that is, when the second target appeared directly after the ?rst target. The other is that the performance was not impaired at Lag 1 (Lag 1 sparing). The present study examined whether the task set of observers determines the occurrence of Lag 1 sparing. The experiment revealed that Lag 1 sparing occurred only when the observers were informed of the relationships of target locations. The present results extend the explanation of Lag 1 sparing by attentional gating ( Visser, Zuvic, Bischof, & Di Lollo, 1999 b) and suggest that this gating system is not stimulus‐driven but subject to goal‐directed control.     

The Rational Reconstruction of Argumentation Referring to Consequences and Purposes in the Application of Legal Rules: A Pragma-Dialectical Perspective

In this paper, the author develops an instrument for the rational reconstruction of argumentation in which a judicial decision is justified by referring to the consequences in relation to the purpose of the rule. The instrument is developed by integrating insights from legal theory and legal philosophy about the function and use of arguments from consequences in relation to the purpose of a rule into a pragma-dialectical framework. Then, by applying the instrument to the analysis of examples from legal practice, it is demonstrated that the instrument can offer a heuristic and critical tool for the analysis and evaluation of legal argumentation that can ‘bridge’ the gap between more abstract discussions of forms of legal argumentation on the one hand, and legal arguments as they occur in actual legal practice on the other hand.

Priority and Time

There is a puzzle about how to understand the conclusion of a successful instance of practical reasoning. Do the considerations adduced in reasoning rationalize the particular doing of an action, as Aristotle is sometimes interpreted as claiming? Or does reasoning conclude in the formation of an attitude – an intention, say – that has an action-type as its content? This paper attempts to clarify what is at stake in that debate and defends the latter view against some of its critics.     

When the ordinary seems unexpected: evidence for incremental physical knowledge in young infants

According to a recent account of infants' acquisition of their physical knowledge, the incremental-knowledge account, infants form distinct event categories, such as occlusion, containment, support, and collision events. In each category, infants identify one or more vectors which correspond to distinct problems that must be solved. For each vector, infants acquire a sequence of variables that enables them to predict outcomes within the vector more and more accurately over time. This account predicts that infants who have acquired only a few of the variables in a sequence should err in two ways in violation-of-expectation tasks: (1) they should view impossible events consistent with their incomplete knowledge as expected (errors of omission), and (2) they should view possible events inconsistent with their incomplete knowledge as unexpected (errors of commission). Many reports have shown that infants who have not yet identified a variable in an event category produce errors of omission: they fail to view impossible events involving the variable as unexpected. However, there has been no report revealing errors of commission in infants' responses to possible events. The present research examined whether 3- and 2.5-month-old infants, whose knowledge of occlusion events is very limited, would produce errors of commission as well as errors of omission when responding to these events. At 3 months of age, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its upper edge. At 2.5 months, infants viewed as unexpected a possible event in which a tall cylinder became visible when passing behind a tall screen with a very large opening extending from its lower edge. These findings provide a new kind of evidence for the incremental-knowledge account, and more generally for the notion that infants, like older children and adults, engage in rule-based reasoning about physical events.     

群组成员行动目标的一致性对群体实体性的影响:动作形式一致性的调节作用

群体被视为一个有机整体的特性被称为群体实体性。研究从行为的行动目标和动作形式两个特征维度出发,探讨了行动目标一致性和动作形式一致性如何共同作用于群体实体性。结果发现,在不同群体规模下,群体成员具有一致目标的群体实体性均高于不一致条件,但只有当行为发生在群体情景且符合合理性原则时,动作形式一致性对该影响关系才起到调节作用。该结果表明,只有当行为发生在群体情景且符合合理性原则时,行动目标和动作形式才联合作用于群体实体性。     

From Patterns To Prosperity: A Review Of Rachlin’s The Science Of Self-control.

The Science of Self‐Control (Rachlin, 2000) presents a clear overview of research and theory on self‐control, emphasizing important recent research by Rachlin and his students on temporally extended behavioral patterning as an aid to curbing impulsive decisions. We found the book well suited as a textbook in a graduate seminar on self‐control, particularly because it lucidly presents several provocative ideas about self‐control, decision making, addiction, and general theories of behavior. Of particular interest are his discussion of the “primrose path” to addiction and his behavioral research on the “prisoner's dilemma” as it relates to self‐control. Although we take some issue with teleological behaviorism, the theory of behavior advocated by Rachlin, we recommend this book to anyone interested in self‐control.     

Action, verbal response and spatial reasoning

Studies have shown that perception of distance, orientation and size can be dissociated from action tasks. The action system seems to possess more veridical, unbiased information than the perceptual/verbal system. The current study examines the nature of the distinction between action and verbal responses in a spatial reasoning task. Participants imagined themselves facing different orientations and either pointed to where other objects would be, or verbally reported their egocentric directions (e.g., "50 degrees to my left"). When using pointing responses, RT and error increased as a function of the angular disparity between the imagined heading and their actual heading. However, when using verbal responses, performance was not affected by angular disparity, suggesting that participants knew the direction of the targets from the imagined perspective but could not point to them directly. The verbal and action systems have fundamentally different information or processes rather than quantitatively different ones.
