Visual crowding: a fundamental limit on conscious perception and object recognition

Crowding, the inability to recognize objects in clutter, sets a fundamental limit on conscious visual perception and object recognition throughout most of the visual field. Despite how widespread and essential it is to object recognition, reading and visually guided action, a solid operational definition of what crowding is has only recently become clear. The goal of this review is to provide a broad-based synthesis of the most recent findings in this area, to define what crowding is and is not, and to set the stage for future work that will extend our understanding of crowding well beyond low-level vision. Here we define six diagnostic criteria for what counts as crowding, and further describe factors that both escape and break crowding. All of these lead to the conclusion that crowding occurs at multiple stages in the visual hierarchy.     

The impact of task-irrelevant emotional stimuli on attention in three domains

Whether task-irrelevant emotional stimuli facilitate or disrupt attention performance may depend on a range of factors, such as emotion type, task difficulty, and stimulus duration. Few studies, however, have systematically examined the influence of these factors on attention performance. Sixty-three adults, scoring within a normative range for mood and anxiety symptoms, completed either an easy or difficult version of an attention task measuring three aspects of attention performance: alerting, orienting, and executive attention. Results showed that in the easy task only, threatening versus nonthreatening task-irrelevant emotional faces facilitated orienting regardless of stimulus duration. These effects were no longer significant during the difficult condition. When the easy and difficult conditions were examined together, duration effects emerged such that stimuli of longer durations lead to greater interference, although effects were nonlinear. Findings illustrate that threat-relevant emotional stimuli facilitate attention during tasks with low cognitive load, but underscore the importance of considering a range of task parameters. Results are discussed in the context of adaptive and maladaptive emotion-attention interactions.     

West vs. West like East vs. West? A comparison between Italian and US American context sensitivity and Fear of Isolation

Easterners tend to process information more holistically than Westerners. Kim and Markman (J Exp Soc Psychol 42(3):350–364, 2006) suggest that these differences are rooted in higher chronic levels of Fear of Isolation (FOI) for those cultures that process information more holistically. The goal of this study was to determine if these differences and their suggested cause could be found with two different Western cultures. Testing Italian (IT) and US American (US) adults, we found that IT participants processed information more holistically and had a higher chronic level of FOI than US participants; furthermore, the manipulation of FOI affected context sensitivity more for IT than for US participants. The results demonstrate that IT participants were more similar to previous research with Eastern populations than with Western populations (Kim and Markman in J Exp Soc Psychol 42(3):350–364, 2006) and indicate a within-Western culture difference for reasoning styles and support the hypothesis that this difference is due to different chronic levels of FOI.     

From glamour-oriented idolatry to achievement-oriented idolatry: A framing experiment among adolescents in Hong Kong and Shenzhen

The present study examined the framing effect of two modes of idolatry among a sample of 1095 secondary school students in Hong Kong and Shenzhen. Two experimental conditions were set up: in the glamour frame condition, subjects were exposed to frames that enhanced perfection and mystification of idols' personal or ideological characteristics; in the achievement frame condition, subjects were exposed to frames that enhanced emulation and identification of idols' pro-social behaviours or desirable dispositional traits. The experiment selected a prominent pop music and movie star well known in Chinese societies, Andy Lau, as the target idol. Subjects showed a consistently and significantly greater desire to glorify, idealize, identify with, emulate, and attach to Andy Lau in the achievement frame condition than in the glamour frame condition. The finding suggests that an achievement frame can heighten young people's adoration of an idol by emphasizing the idol's achievement processes. This suggestion is favourable to the possibility of transforming an idol into a role model for young people to learn to pursue career success.     

Perception as evidence accumulation and Bayesian inference: insights from masked priming

The authors argue that perception is Bayesian inference based on accumulation of noisy evidence and that, in masked priming, the perceptual system is tricked into treating the prime and the target as a single object. Of the 2 algorithms considered for formalizing how the evidence sampled from a prime and target is combined, only 1 was shown to be consistent with the existing data from the visual word recognition literature. This algorithm was incorporated into the Bayesian Reader model (D. Norris, 2006), and its predictions were confirmed in 3 experiments. The experiments showed that the pattern of masked priming is not a fixed function of the relations between the prime and the target but can be changed radically by changing the task from lexical decision to a same-different judgment. Implications of the Bayesian framework of masked priming for unconscious cognition and visual masking are discussed.     

Skating down a steeper slope: fear influences the perception of geographical slant

Previous studies have shown that conscious awareness of hill slant is overestimated, but visually guided actions directed at hills are relatively accurate. Also, steep hills are consciously estimated to be steeper from the top than the bottom, possibly because they are dangerous to descend. In the present study, participants stood at the top of a hill either on a skateboard or a wooden box of the same height. They gave three estimates of the slant: a verbal report, a visually matched estimate, and a visually guided action. Fear of descending the hill was also assessed. Those participants who were scared (by the skateboard) consciously judged the hill to be steeper than unafraid participants. However, the visually guided action measure was accurate across conditions. These results suggest that explicit awareness of slant is influenced by the fear associated with a potentially dangerous action that could be performed on the hill.     

Action Research: A Missing Component in the Emergence of Social and Cross‐Cultural Psychology as a Fully Inter‐Connected Global Enterprise

Action research, as envisaged by Lewin, uses research to solve a social problem and provide theoretical knowledge. It involves a cyclical–spiral of planning, action, and evaluation with feedback between parties, taking into account power and value differences and empowering change agents. This has been all but abandoned by social psychologists today. Contemporary ‘participatory’ action research has migrated to fields like education and development and community studies that emphasize a social constructionist epistemology with a qualitative approach of recording bottom‐up processes of social change and community self‐awareness. The globalization of psychology affords new opportunities for a return to more top‐down Lewinian traditions, where academics in the developing world – embedded within a cultural milieu of interconnectedness and relatively exempt from pressures to publish or perish – can work together with academics in wealthy countries to produce a process oriented psychology that is capable of making a difference under conditions of climate change and the end of cheap oil. Asian social psychology, where strongly indigenous psychologies have taken root in growing economies, may take a leading role in this movement.     

Evidence-based Kernels: Fundamental Units of Behavioral Influence

This paper describes evidence-based kernels, fundamental units of behavioral influence that appear to underlie effective prevention and treatment for children, adults, and families. A kernel is a behavior-influence procedure shown through experimental analysis to affect a specific behavior and that is indivisible in the sense that removing any of its components would render it inert. Existing evidence shows that a variety of kernels can influence behavior in context, and some evidence suggests that frequent use or sufficient use of some kernels may produce longer lasting behavioral shifts. The analysis of kernels could contribute to an empirically based theory of behavioral influence, augment existing prevention or treatment efforts, facilitate the dissemination of effective prevention and treatment practices, clarify the active ingredients in existing interventions, and contribute to efficiently developing interventions that are more effective. Kernels involve one or more of the following mechanisms of behavior influence: reinforcement, altering antecedents, changing verbal relational responding, or changing physiological states directly. The paper describes 52 of these kernels, and details practical, theoretical, and research implications, including calling for a national database of kernels that influence human behavior.     

Shortlist B: a Bayesian model of continuous speech recognition

A Bayesian model of continuous speech recognition is presented. It is based on Shortlist (D. Norris, 1994; D. Norris, J. M. McQueen, A. Cutler, & S. Butterfield, 1997) and shares many of its key assumptions: parallel competitive evaluation of multiple lexical hypotheses, phonologically abstract prelexical and lexical representations, a feedforward architecture with no online feedback, and a lexical segmentation algorithm based on the viability of chunks of the input as possible words. Shortlist B is radically different from its predecessor in two respects. First, whereas Shortlist was a connectionist model based on interactive-activation principles, Shortlist B is based on Bayesian principles. Second, the input to Shortlist B is no longer a sequence of discrete phonemes; it is a sequence of multiple phoneme probabilities over 3 time slices per segment, derived from the performance of listeners in a large-scale gating study. Simulations are presented showing that the model can account for key findings: data on the segmentation of continuous speech, word frequency effects, the effects of mispronunciations on word recognition, and evidence on lexical involvement in phonemic decision making. The success of Shortlist B suggests that listeners make optimal Bayesian decisions during spoken-word recognition.     

Ethical Aspects of Spirituality in Counseling

The authors review the professional literature related to spirituality and ethics in counseling. The American Counseling Association's (1995, 2005) code of ethics was used as a basis for exploring the possibilities and limits/boundaries appropriate for discussion of spirituality in counseling. Implications for practice and research are discussed.
