The group's absence norm and commitment to the group as predictors of group member absence in the next session: an actor-partner analysis

The group's absence norm, a construct from the applied psychology literature, was used to examine session absences in personal growth groups. Rather than examining the absence norm statically, we modeled it dynamically as a time-varying covariate (Tasca et al., 2010). We also examined moderation by modeling the interaction of the absence norm and the group member's commitment to the group in predicting the group member's absence in the next group session. Session absences in 1,722 group sessions for 66 group members in 9 interpersonal growth groups were modeled using Kenny, Mannetti, Pierro, Livi, and Kashy's (2002) adaptation of the Actor-Partner Interdependence model. Specifically, a 3-level model (sessions within group members within groups) examined the relationship of the group's absence norm (average previous absences of the other group members), commitment to the group (previous absences of the group member), and the interaction of the group's absence norm and commitment to the group on absence in the next session. As we hypothesized, (a) a greater number of previous individual absences (low commitment) increased the probability of a member being absent the next session, (b) the higher the group's absences norm, the greater the probability that an individual group member would be absent the next session, and (c) individual group members who were more committed to the group were more influenced by the group's absences norm than were group members less committed to the group. Implications for research and practice are discussed.     

Reading through a noisy channel: why there's nothing special about the perception of orthography

The goal of research on how letter identity and order are perceived during reading is often characterized as one of "cracking the orthographic code." Here, we suggest that there is no orthographic code to crack: Words are perceived and represented as sequences of letters, just as in a dictionary. Indeed, words are perceived and represented in exactly the same way as other visual objects. The phenomena that have been taken as evidence for specialized orthographic representations can be explained by assuming that perception involves recovering information that has passed through a noisy channel: the early stages of visual perception. The noisy channel introduces uncertainty into letter identity, letter order, and even whether letters are present or absent. We develop a computational model based on this simple principle and show that it can accurately simulate lexical decision data from the lexicon projects in English, French, and Dutch, along with masked priming data that have been taken as evidence for specialized orthographic representations.     

New insights into the impact of digital signage as a retail atmospheric tool

This article investigates the previously little‐researched role of digital signage (DS) in retail atmospherics, using an environmental psychology framework, drawing support from the Limited Capacity Model of Mediated Message Processing (LCM). DS consists of screen displays in public spaces showing video. The method consisted of a structured questionnaires quasi‐experiment (n = 357), comparing before and after DS installation against an unchanged control mall. Results demonstrate the effectiveness of DS, which has a positive effect on shoppers' approach behaviors such as spending, mediated by perceptions of the retail environment and positive affect. Results are limited as the DS screens content was information based, whereas according to LCM, people pay more attention to emotion‐eliciting communications. The results have practical implications as DS appeals to employed shoppers. This study contributes to theory by providing a rare longitudinal environmental psychology study of the effects of an atmospheric stimulus on real shoppers in a real retail context.

Dissociating positive and negative influences of verbal processing on the recognition of pictures of faces and objects

Four experiments investigated the role of verbal processing in the recognition of pictures of faces and objects. We used (a) a stimulus-encoding task where participants learned sequentially presented pictures in control, articulatory suppression, and describe conditions and then engaged in an old-new picture recognition test and (b) a poststimulus-encoding task where participants learned the stimuli without any secondary task and then either described or not a single item from memory before the recognition test. The main findings were as follows: First, verbalization influenced picture recognition. Second, there were contrasting influences of verbalization on the recognition of faces, compared with objects, that were driven by (a) the stage of processing during which verbalization took place (as assessed by the stimulus-encoding and poststimulus-encoding tasks), (b) whether verbalization was subvocal (whereby one goes through the motions of speaking but without making any sound) or overt, and (c) stimulus familiarity. During stimulus encoding there was a double dissociation whereby subvocal verbalization interfered with the recognition of faces but not objects, while overt verbalization benefited the recognition of objects but not faces. In addition, stimulus familiarity provided an independent and beneficial influence on performance. Post stimulus encoding, overt verbalization interfered with the recognition of both faces and objects, and this interference was apparent for unfamiliar but not familiar stimuli. Together these findings extend work on verbalization to picture recognition and place important parameters on stimulus and task constraints that contribute to contrasting beneficial and detrimental effects of verbalization on recognition memory.     

The role of source memory in older adults' recollective experience

Younger adults' "remember" judgments are accompanied by better memory for the source of an item than "know" judgments. Furthermore, remember judgments are not merely associated with better memory for individual source features but also with bound memory for multiple source features. However, older adults, independent of their subjective memory experience, are generally less likely to "bind" source features to an item and to each other in memory (i.e., the associative deficit). In two experiments, we tested whether memory for perceptual source features, independently or bound, is also the basis for older adults' remember responses or if their associative deficit leads them to base their responses on other types of information. The results suggest that retrieval of perceptual source features, individually or bound, forms the basis for younger but not for older adults' remember judgments even when the overall level of memory for perceptual sources is closely equated (Experiment 1) and when attention is explicitly directed to the source information at encoding (Experiment 2).

A neutral face is not neutral even if you have not seen it: social anxiety disorder and affective priming with facial expressions

Cognitive theories suggest that social anxiety disorder (SAD) is characterized by biased processing of negative facial expressions. Recently, however, it has been proposed that the fear of positive evaluation may play an additional, important role. In order to investigate which specific expressions evoke biased processing, 15 patients diagnosed with SAD and 15 non-anxious controls (NACs) completed an affective priming procedure: they rated neutral symbols which were preceded by sub-optimally presented primes of angry, neutral, and smiling faces. Patients with SAD rated the symbols significantly more negatively than NACs when they were primed with a neutral face. In addition, SAD patients tended to rate all symbols significantly more negatively suggesting that all faces (negative, positive, and neutral) are threatening to SAD patients.     

Data-driven sequence learning or search: What are the prerequisites for the generation of explicit sequence knowledge?

In incidental sequence learning situations, there is often a number of participants who can report the task-inherent sequential regularity after training. Two kinds of mechanisms for the generation of this explicit knowledge have been proposed in the literature. First, a sequence representation may become explicit when its strength reaches a certain level (Cleeremans, 2006), and secondly, explicit knowledge may emerge as the result of a search process that is triggered by unexpected events that occur during task processing and require an explanation (the unexpected-event hypothesis; Haider & Frensch, 2009). Our study aimed at systematically exploring the contribution of both mechanisms to the generation of explicit sequence knowledge in an incidental learning situation. We varied the amount of specific sequence training and inserted unexpected events into a 6-choice serial reaction time task. Results support the unexpected-event view, as the generation of explicit sequence knowledge could not be predicted by the representation strength acquired through implicit sequence learning. Rather sequence detection turned out to be more likely when participants were shifted to the fixed repeating sequence after training than when practicing one and the same fixed sequence without interruption. The behavioral effects of representation strength appear to be related to the effectiveness of unexpected changes in performance as triggers of a controlled search.     

Electronic Friend or Virtual Foe: Exploring the Role of Competitive and Cooperative Multiplayer Video Game Modes in Fostering Enjoyment

Industry and scholarly sources both argue that multiplayer gaming and competition are important factors in creating enjoyment, but relatively little empirical work demonstrates this claim. This study uses an experimental design (N = 139) to evaluate the effects of different multiplayer modes on enjoyment, allowing participants to interact naturally with a confederate partner and manipulating both game mode and partner behavior in a game of Madden '08. Results show that enjoyment is significantly enhanced by the combination of competitive play and a friendly partner, and demonstrate that the quality of interpersonal interaction only partly accounts for this.
