When is a picture?

Philosophical discussions of depiction sometimes suffer from a lack of differentiation between several questions concerning the ‘nature’ of pictorial representation. To provide a suitable framework I distinguish six such questions and several levels on which one might want to proceed in order to answer some of them. With this background, I reconstruct Goodman's and Elgin's answer to the specific question: ‘What distinguishes the pictorial from the verbal or linguistic?’ I try to reveal some major motivations behind their system-oriented approach and to indicate some reasons why a strategy of this kind is to a certain extent mandatory to grasp the ‘nature of the pictorial’. The system-relative and functional character of depiction has to be captured by every adequate theory.     

When does generation enhance memory for location?

Generation is thought to enhance both item-specific and relational processing of generated targets as compared with read words (M. A. McDaniel & P. J. Waddill, 1990). Generation facilitates encoding of the cue-target relation and sometimes boosts encoding of relations across list items. Of interest is whether generation can also increase the encoding of target-location associations. Because the literature on this point is mixed, 3 procedural differences between 2 studies (E. J. Marsh, G. Edelman, & G. H. Bower, 2001; N. W. Mulligan, 2004) were identified and manipulated. A positive generation effect was found for location memory, but this effect was reduced when subjects wrote down the study words and when the filler task involved generation. Generation can enhance location memory in addition to item memory but only if the experimental parameters do not interfere with the processing benefits of generation.     

When is a Deleuzian becoming ?

Much has been written recently about the Deleuzian concept of becoming. Most of that writing, especially in feminist criticism, has drawn from the later collaborations with Guattari. However, the concept of a becoming arises earlier and appears more consistently across the trajectory of Deleuze's work than the discussion of specific becomings might lead one to believe. In this paper, I trace the concept of becoming in Deleuze's work, and specifically in the earlier works. By doing so, I hope to shed some light on the specific becomings that are the focus of the collaborative work with Guattari, and to deepen an understanding of the concept in general.     

When is a Concrete Property Basic?

We more or less understand how composition works in the case of objects. We cement bricks together to build a wall. We stir together red paint and yellow paint to get orange paint. In both cases, one way or another, A = B + C. This paper examines composition in the case of concrete natural properties. It explains why property composition is so much less straightforward than object composition. Then it distinguishes strictly basic properties (like the mass of an electron), compositely basic properties (like the mass of a planet), and fully non-basic properties (like the saltiness of blood). It shows how strictly basic properties compose, or result in, compositely basic and fully non-basic properties, which differ from, yet depend for their natures on, the strictly basic properties they result from. It explains the characteristics and differences of these types of properties. It notes that the existence of compositely basic and non-basic properties grounds an argument for the genuine existence of composite properties as well as the composite objects they characterize. Finally, it defends the usefulness of these distinctions by identifying projects they assist, and by applying them both to mark off distinct metaphysical views too often conflated and to correct sundry metaphysical mistakes.     

When is a weight not illusory?

Weight illusions occur whenever some aspect of an object--such as its size, material or colour--arouses the expectation that its weight will be heavier or lighter than it actually is. The direction of the illusion normally contrasts with the expected weight. When objects are hidden from sight and lifted by strings they can provide no misleading cues, and a correct weight-expectation should be achieved after one or two trials. When a visible object has the same physical and apparent weight as a hidden object, it can be defined as non-illusory. Weighted tins and polystyrene blocks of various sizes were compared with hidden weights. Tins were found to be non-illusory when their density was about 1.7, and polystyrene blocks when their density was about 0.14.

Weight illusions may be due to a central scaling process which enables a wide range of weights to be estimated, different ranges being selected according to the expected value of the weight. If the selected range is inappropriate an illusion occurs. Changes in expected value could also allow for the operation of “weight-constancy” during changes in proprioceptive stimulation.     

When is a cognitive system embodied?

For cognitive systems, embodiment appears to be of crucial importance. Unfortunately, nobody seems to be able to define embodiment in a way that would prevent it from also covering its trivial interpretations such as mere situatedness in complex environments. The paper focuses on the definition of embodiment, especially whether physical embodiment is necessary and/or sufficient for cognitive systems. Cognition is characterized as a continuous complex process rather than ahistorical logical capability. Furthermore, the paper investigates the relationship between cognitive embodiment and the issues of understanding, representation and task specification.     

“None of the above” as a correct and incorrect alternative on a multiple-choice test: Implications for the testing effect

Both positive and negative testing effects have been demonstrated with a variety of materials and paradigms (Roediger & Karpicke, 2006b). The present series of experiments replicate and extend the research of Roediger and Marsh (2005) with the addition of a “none-of-the-above” response option. Participants (n=32 in both experiments) read a set of passages, took an initial multiple-choice test, completed a filler task, and then completed a final cued-recall test (Experiment 1) or multiple-choice test (Experiment 2). Questions were manipulated on the initial multiple-choice test by adding a “none-of-the-above” response alternative (choice “E”) that was incorrect (“E” Incorrect) or correct (“E” Correct). The results from both experiments demonstrated that the positive testing effect was negated when the “none-of-the-above” alternative was the correct response on the initial multiple-choice test, but was still present when the “none-of-the-above” alternative was an incorrect response.     

When do nonwords activate semantics? Implications for models of visual word recognition

Three lexical decision experiments examined the conditions in which nonwords activate semantics. Lexical decisions to targets (e.g., CAT) were faster when preceded by semantically related nonword primes (e.g., DEG derived from DOG) when the prime was brief and masked; this nonword priming effect was eliminated when the prime was presented for a longer duration. These results are discussed in the context of both parallel distributed processing models and the idea that the occurrence of nonword priming depends upon subjects being unable to verify the identity of the prime.     

When is search for a static target among dynamic distractors efficient?

Intuitively, dynamic visual stimuli, such as moving objects or flashing lights, attract attention. Visual search tasks have revealed that dynamic targets among static distractors can indeed efficiently guide attention. The present study shows that the reverse case, a static target among dynamic distractors, allows for relatively efficient selection in certain but not all cases. A static target was relatively efficiently found among distractors that featured apparent motion, corroborating earlier findings. The important new finding was that static targets were equally easily found among distractors that blinked on and off continuously, even when each individual item blinked at a random rate. However, search for a static target was less efficient when distractors abruptly varied in luminance but did not completely disappear. The authors suggest that the division into the parvocellular pathway dealing with static visual information, on the one hand, and the magnocellular pathway common to motion and new object onset detection, on the other hand, allows for efficient filtering of dynamic and static information.     

When is a compliment not a compliment? Evaluating expressions of positive stereotypes

Unlike negative stereotypes, positive stereotypes are often perceived as admirable qualities, and expressions of such beliefs may be intended as compliments toward group members. Two experiments were conducted to examine how the targets of positive stereotypes evaluate others who express such stereotypic “compliments.” In Study 1, Black participants evaluated a White student who praised the athletic ability of African Americans more negatively than a control condition. In Study 2, Black and White participants watched an interracial interaction that involved the White actor expressing positive stereotypes or a control interaction with no stereotypes. In the positive stereotype condition, Black participants evaluated the White actor and the interaction as a whole more negatively than did White participants, but there were no differences in the control condition. The implications for the perpetuation of interracial distrust and avoidance are discussed.     

Can a modified lineup procedure improve the usefulness of confidence?

In a face recognition, mini-lineup experiment we examined two aspects of the use of confidence about lineups. We modified the lineup procedure attempting to eliminate the difference in confidence–accuracy relationship between positive (old or identification) and negative (new or not present) decisions. In the modified procedure, participants: (1) selected the lineup member that best matched their memory of the target; (2) rated their confidence that the best match was indeed the target; and (3) indicated (yes/no) whether the best match was the target. Although the modified procedure produced higher accuracy than a standard simultaneous procedure, there was no evidence that it affected the confidence–accuracy relationship. Additionally, the modified procedure also allowed us to compare the extent to which confidence ratings versus binary recognition decisions better discriminated studied from unstudied faces. The results revealed a clear advantage for confidence, but indicated that binary responses were also a unique predictor.     

When is the infrahumanization to a threatening outgroup higher? Effects of the ambiguity of situation and the empathy with ingroup

Infrahumanization researchs have shown that people attribute their ingroup exclusively human features, for example, the ability to experience secondary emotions. This bias lead people to deny this ability to outgroup and, consequently, to infrahumanize them. However, it would have conditions in which the infrahumanization is intensified. The aim of this study is to determine if there are characteristics in a threatening situation that influence in the level in which ingroup infrahumanize the outgroup. Two histories were constructed; in them, the outgroup committed a violent action against the ingroup, and as the degree of certainty about the perpetration, so the level of empathy with the victim were manipulated. The results show that when there are empathy with the victim and ambiguity about the perpetration, the infrahumanization to outgroup is higher.     

When parents have a history of conduct disorder: how is the caregiving environment affected?

Individuals with early-emerging conduct problems are likely to become parents who expose their children to considerable adversity. The current study tested the specificity of and alternative explanations for this trajectory. The sample included 246 members of a prospective, 30-year cohort study and their 3-year-old children. Parents who had a history of conduct disorder were specifically at elevated risk for socioeconomic disadvantage and relationship violence, but suboptimal parenting and offspring temperament problems were common to parents with any history of disorder. Recurrent disorder, comorbidity, and adversity in the family of origin did not fully account for these findings. The cumulative consequences of early-onset conduct disorder and assortative mating for antisocial behavior may explain the long-term effects of conduct disorder on young adult functioning.     

When is Nothing Something? Editorial for the Null Results Special Issue of Journal of Business and Psychology

This special issue is focused on how null results can meaningfully advance science and practice. This editorial describes some of the unique aspects of creating a special issue devoted to null results, offers opinions regarding why and under what conditions null results should be valued, and offers recommendations for key stakeholders (i.e., editors, reviewers, and authors) in the publication enterprise with respect to submitting and evaluating research with null findings. This editorial also provides summaries of the papers included in this special issue with emphasis on how they serve as example for what constitutes meaningful null results.     

Relative or absolute? Implications and consequences of the measures adopted to investigate motor overflow

Motor overflow is involuntary overt movement or covert muscle activity that cooccurs with voluntary movement. Overflow is present in several pathological conditions, as well as in neurologically healthy children and older adults, and can be induced in healthy young adults under effortful conditions. This motor phenomenon may provide insight into the underlying mechanisms and kinetic characteristics of voluntary and involuntary motor control in various populations. Although often measured behaviorally using force transduction techniques, different methods of calculating and presenting such overflow data have resulted in seemingly contradictory findings, with limited discussion of the advantages and limitations of different approaches. In this article, the authors examined the relevant literature to highlight significant methodological considerations for authors and readers conducting or appraising this type of research. Issues regarding the interpretation and reporting of findings are also discussed. Researchers are encouraged to continue using behavioral measures to create well-defined variables that enable the study of the kinematic characteristics of overflow, as these may offer promising new ways forward in better characterizing and understanding this intriguing movement phenomenon.     

Toward an Evolution of Mind: Implications for the Faithful?

Ever since its inception, Charles Darwin's theory of evolution by natural selection has challenged assumptions about the nature of humankind and human institutions. It did not escape the notice of Darwin, sympathetic allies, or hostile contemporaries that his theory had profound implications for ethics and theology. In this paper I review some current sociobiological hypotheses about the mind that are based on the theory that the human mind is primarily a social tool. Many researchers now believe that both complex human within-group cooperation and between-group competition are the anvils that may have shaped the modules of the mind. Given this evolutionary theory of the mind, the Darwinian challenge to theism, ethics, and faith is now being relaunched with a vengeance. However, I suggest that modern physics, evolutionary biology, and cognitive science all seem to fit nicely into the atheistic and phenomenological niche defined by Buddhism.     

Hume and the Problem of Paternalism: When is Humanity Sufficient?

Hume states that if a group of powerless, rational creatures lived amongst human beings, then humans would be required to treat this species with humanity but not with justice. Michael Ridge has argued that this implies humans would be required to engage in a morally dubious form of paternalism toward this imagined species. I argue that a proper understanding of why this imagined species is excluded from the scope of justice shows Hume has a plausible moral reason for requiring paternalism in this instance. The reason the imagined species is excluded is that they are incapable of feeling what I term “the pain of dependence,” or unease arising from complete dependence upon those who are more powerful. Those capable of the pain of dependence will have reason to resent exclusion from the scope of justice (and the accompanying susceptibility to paternalism). However, I contend that Hume did not think that the imagined species was capable of feeling the pain of dependence. This means that the imagined species would not consider themselves wronged when subject to paternalistic treatment, and, consequently, there is good reason to think the sort of paternalism that Hume's theory allows is not morally objectionable.
