Toward a scalable holographic word-form representation

Phenomena in a variety of verbal tasks—for example, masked priming, lexical decision, and word naming—are typically explained in terms of similarity between word-forms. Despite the apparent commonalities between these sets of phenomena, the representations and similarity measures used to account for them are not often related. To show how this gap might be bridged, we build on the work of Hannagan, Dupoux, and Christophe, Cognitive Science 35:79-118, (2011) to explore several methods of representing visual word-forms using holographic reduced representations and to evaluate them on their ability to account for a wide range of effects in masked form priming, as well as data from lexical decision and word naming. A representation that assumes that word-internal letter groups are encoded relative to word-terminal letter groups is found to predict qualitative patterns in masked priming, as well as lexical decision and naming latencies. We then show how this representation can be integrated with the BEAGLE model of lexical semantics (Jones & Mewhort, Psychological Review 114:1–37, 2007) to enable the model to encompass a wider range of verbal tasks.     

Chicken soup really is good for the soul: "comfort food" fulfills the need to belong

Theories of social surrogacy and embodied cognition assume that cognitive associations with nonhuman stimuli can be affectively charged. In the current research, we examined whether the "comfort" of comfort foods comes from affective associations with relationships. Two experiments support the hypotheses that comfort foods are associated with relationships and alleviate loneliness. Experiment 1 found that the consumption of comfort foods automatically activates relationship-related concepts. Experiment 2 found that comfort foods buffer against belongingness threats in people who already have positive associations with relationships (i.e., are secure in attachment style). Implications for social surrogacy, need to belong, embodied cognition, and eating behavior are discussed.     

Anticipation from biological motion: the goalkeeper problem

People can often anticipate the outcome of another person's actions based on visual information available in the movements of the other person's body. We investigated this problem by studying how goalkeepers anticipate the direction of a penalty kick in soccer. The specific aim was to determine whether the information used to anticipate kick direction is best characterized as local to a particular body segment or distributed across multiple segments. In Experiment 1, we recorded the movements of soccer players as they kicked balls into a net. Using a novel method for analyzing motion capture data, we identified sources of local and distributed information that were reliable indicators of kick direction. In Experiments 2 and 3, subjects were presented with animations of kickers' movements prior to foot-to-ball contact and instructed to judge kick direction. Judgments were consistent with the use of distributed information, with a possible small contribution of local information.     

Indirect majority and minority influence: An exploratory study

In a 2 × 2 design, 85 subjects were asked to estimate the size of angles (direct influence) that were either 90 or 85°, after being confronted with incorrect judgements of a majority (88 per cent) or a minority (12 per cent) of people estimating the angles at 50°. Additionally, pre- and post-test measures were used to establish indirect influence on subjects' judgements pertaining to acute angles (i.e. on the estimation of the length of lines constituting the angles, and on the imaginary weight of figures represented by these angles). Overall, little direct influence is observed. This may partly be due to the introduction of a denial of the credibility of the source in all conditions. In fact, some evidence of direct influence is only found in the majority–85° angles condition. An instance of indirect influence (on the estimation of length of lines) appeared as the result of a majority stance when the angles in the experimental phase were 90°. When these angles were 85°, indirect minority influence (on the estimation of weight of figures) was observed. These effects had been predicted on the basis of the hypothesis stating that indirect majority influence would be possible when subjects expected consensus on the correct response (in the 90° angles condition), without being able to reach consensus at the manifest level (because of the denial and the restriction imposed by the clear shape of 90° angles). Indirect minority influence was hypothesized to be stronger in a situation that allows for diverse responses (i.e. for 85° angles).     

Rorschach Comprehensive System data for a sample of 75 Danish 9-year-old children: a pilot study

This article provides a normative study documenting how 75 Danish nonpatient 9-year-old children respond to the Rorschach test. The children were selected randomly from nine different parts of Denmark and tested with the Rorschach by 10 different psychologists. All examiners were familiar with the Comprehensive System (CS; Exner, 2003), and before the data collection they participated in a 3-day workshop performed by the research group that focused on administration, inquiry, and scoring issues. Among the results are an average R of 23.6 and an average Lambda of 2.01 (median = 1.18). Slightly more than 60% of the sample had an Avoidant style (63%); 41% had a CDI of 4 or 5; and 33% were positive on the HVI. In terms of perception and thinking, average values were .44 for X+%, .27 for X-%, and 9.4 for the WSum6.     

A General Methodology for the Translation of Behavioral Terms into Vernacular Languages

As the field of behavior analysis expands internationally, the need for comprehensive and systematic glossaries of behavioral terms in the vernacular languages of professionals and clients becomes crucial. We created a Spanish-language glossary of behavior-analytic terms by developing and employing a systematic set of decision-making rules for the inclusion of terms. We then submitted the preliminary translation to a multi-national advisory committee to evaluate the transnational acceptability of the glossary. This method led to a translated corpus of over 1200 behavioral terms. The end products of this work included the following: (a) a Spanish-language glossary of behavior analytic terms that are publicly available over the Internet through the Behavior Analyst Certification Board and (b) a set of translation guidelines summarized here that may be useful for the development of glossaries of behavioral terms into other vernacular languages.
