There goes the neighbourhood: Contextual control over the breadth of lexical activation when reading aloud

There are currently two computational accounts of how the time to read pseudohomophones (like BRANE) and their nonword controls (like FRANE) varies with changes in context. In Reynolds and Besner's (2005) account, readers vary the breadth of lexical activation in response to changes in context. A competing account proposed by Kwantes and Marmurek (2007 Kwantes, P. and Marmurek, H. 2007. Controlling lexical contributions to the reading of pseudohomophones. Psychonomic Bulletin & Review, 14: 373–378. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and independently by Perry, Ziegler, and Zorzi (2007 Perry, C., Ziegler, J. C. and Zorzi, M. 2007. Nested incremental modeling in the development of computational theories: The CDP+ model of reading aloud. Psychological Review, 114: 273–315. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) has readers varying their response criterion in response to changes in context. The present work adjudicates between these two accounts by examining how the effect of neighbourhood density changes as a function of list context when reading pseudohomophones aloud. The results of an experiment and simulations from a leading computational model support the lexical breadth account, but are inconsistent with the response criterion account.     

How to use the diffusion model: Parameter recovery of three methods: EZ, fast-dm, and DMAT

Parameter recovery of three different implementations of the Ratcliff diffusion model was investigated: the EZ model (Wagenmakers, van der Maas, & Grasman, 2007), fast-dm (Voss & Voss, 2007), and DMAT (Vandekerckhove & Tuerlinckx, 2007). Their capacity to recover both the mean structure and individual differences in parameter values was explored. The three methods were applied to simulated data generated by the diffusion model, by the leaky, competing accumulator (LCA) model (Usher & McClelland, 2001) and by the linear ballistic accumulator (LBA) model (Brown & Heathcote, 2008). Results show that EZ and DMAT are better capable than fast-dm in recovering experimental effects on parameters. EZ was best in recovering individual differences in parameter values. When data were generated by the LCA model, the diffusion model estimates obtained with all three methods correlated well with corresponding LCA model parameters. No such one-on-one correspondence could be established between parameters of the LBA model and the diffusion model.     

Measuring resilience among homeless youth: psychometric assessment of the Connor-Davidson Resilience Scale in Ghana

This study validated the psychometric structure of the Connor-Davidson Resilience Scale (CD-RISC; Connor & Davidson, 2003 Connor, K. M., & Davidson, J. R. T. (2003). Development of a New Resilience Scale: The Connor–Davidson Resilience Scale (CD-RISC). Depression and Anxiety, 18, 76–82. doi: 10.1002/da.10113[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) in a sample of 227 homeless youth in Ghana. Principal Component Analysis (PCA) with Varimax rotation was used to extract factor structures. About 62% of the total variance was accounted for by a three-factor structure: personal competence and tenacity, optimism and achievement motivation. Evidence of the external validity of scales was supported by the positive correlation between resilience and perceived social support scores. The CD-RISC appears to yield scores reliable for assessing resilience among homeless youth in a developing world context.     

Naming times and standardized norms for the italian PD/DPSS set of 266 pictures: Direct comparisons with American, English, French, and Spanish published databases

The present study provides Italian normative measures for 266 line drawings belonging to the new set of pictures developed by Lotto, Dell’Acqua, and Job (in press). The pictures have been standardized on the following measures: number of letters, number of syllables, name frequency, within-category typicality, familiarity, age of acquisition, name agreement, and naming time. In addition to providing the measures, the present study focuses on indirect and direct comparisons (i.e., correlations) of the present norms with databases provided by comparable studies in Italian (in which normative data were collected with Snodgrass & Vanderwart’s set of pictures; Nisi, Longoni, & Snodgrass, 2000), in British English (Barry, Morrison, & Ellis, 1997), in American English (Snodgrass & Vanderwart, 1980; Snodgrass & Yuditsky, 1996), in French (Alario & Ferrand, 1999), and in Spanish (Sanfeliu & Fernandez, 1996).     

Intentional Binding is independent of the validity of the action effect's identity

When an action produces an effect, both events are perceived to be shifted in time toward each other. This shift is called Intentional Binding (IB) effect. First evidence shows that this shift does not depend on the statistical predictability of the produced effect's identity (Desantis, Hughes, & Waszak, 2012). We confirm this result by comparing the perceived duration of action–effect intervals before valid and invalid action effects using the method of constant stimuli. The perceived duration of action–effect intervals did not differ for valid and invalid effects. This result was true for different durations of the action–effect interval (Experiments 1–4: 250 ms, Experiments 1 & 2: 400 ms), different effect modalities (Experiments 1 & 3: visual, Experiments 2–4: auditive), and two types of validity variations (Experiments 1 & 2: 80% valid, Experiments 3 & 4: 100% valid vs. random). We validated our results by using a clock paradigm and a numerical duration estimation task (Experiment 4). We conclude that the IB effect is not the result of internal prediction due to action–effect bindings, but might rely on higher-order processes.     

The role of numerical and non-numerical cues in nonsymbolic number processing: Evidence from the line bisection task

In line bisection tasks, adults and children bisect towards the numerically larger of two nonsymbolic numerosities [de Hevia, M. D., & Spelke, E. S. (2009 de Hevia, M. D., & Spelke, E. S. (2009). Spontaneous mapping of number and space in adults and young children. Cognition, 110, 198–207. doi:10.1016/j.cognition.2008.11.003[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Spontaneous mapping of number and space in adults and young children. Cognition, 110, 198–207. doi:10.1016/j.cognition.2008.11.003]. However, it is not clear whether this effect is driven by number itself or rather by visual cues such as subtended area [Gebuis, T., & Gevers, W. (2011 Gebuis, T., & Gevers, W. (2011). Numerosities and space: Indeed a cognitive illusion! A reply to de Hevia and Spelke (2009). Cognition, 121, 248–252. doi:10.1016/j.cognition.2010.09.008[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Numbers and space: Indeed a cognitive illusion! A reply to de Hevia and Spelke (2009 de Hevia, M. D., & Spelke, E. S. (2009). Spontaneous mapping of number and space in adults and young children. Cognition, 110, 198–207. doi:10.1016/j.cognition.2008.11.003[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Cognition, 121, 248–252. doi:10.1016/j.cognition.2010.09.008]. Furthermore, this effect has only been demonstrated with flanking displays of two and nine items. Here, we report three studies that examined whether this “spatial bias” effect occurs across a range of absolute and ratio numerosity differences; in particular, we examined whether the bias would occur when both flankers were outside the subitizing range. Additionally, we manipulated the subtended area of the stimulus and the aggregate surface area to assess the influence of visual cues. We found that the spatial bias effect occurred for a range of flanking numerosities and for ratios of 3:5 and 5:6 when subtended area was not controlled (Experiment 1). However, when subtended area and aggregate surface area were held constant, the biasing effect was reversed such that participants bisected towards the flanker with fewer items (Experiment 2). Moreover, when flankers were identical, participants bisected towards the flanker with larger subtended area or larger aggregate surface area (Experiments 2 and 3). On the basis of these studies, we conclude that the spatial bias effect for nonsymbolic numerosities is primarily driven by visual cues.     

Growin' Grass: Paradise by the Sodium Light

This qualitative study describes members of a little-known and little-researched subculture: small-time marijuana cultivators in the United States. Couched within a symbolic interaction theoretical framework, extensive ethnographic interviews were conducted with eighteen marijuana growers who cultivate cannabis plants in their homes for small sales and personal use. This study creates a typology of growers based on motivation for growing and techniques of cultivation. The authors also illustrate how marijuana growers in this study used various techniques outlined by Sykes and Matza (1957 Sykes , Gresham M. and David Matza . 1957 . “Techniques of Neutralization: A Theory of Delinquency.” American Sociological Review 22 : 664 – 670 .[Crossref], [Web of Science ®] , [Google Scholar]) to neutralize their involvement in a deviant and illegal activity.     

Perceived Discrimination and Health-Related Quality of Life: Testing the Reserve Capacity Model in Hispanic Americans

ABSTRACT

This study tested aspects of the Reserve Capacity Model (Gallo & Matthews, 2003 Gallo, L. C. and Matthews, K. A. 2003. Understanding the association between socioeconomic status and physical health: Do negative emotions play a role?. Psychological Bulletin, 129: 10–51. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Gallo, Penedo Espinosa de los Monteros, & Arguelles, 2009 Gallo, L. C., Penedo, F. J., Espinosa de los Monteros, K. and Arguelles, W. 2009. Resiliency in the face of disadvantage: Do Hispanic cultural characteristics protect health outcomes?. Journal of Personality, 77: 1707–1746. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) as a means of understanding disparities in health-related quality of life appraisals among Hispanic Americans. Questionnaire data were collected from 236 Hispanic participants, including measures of perceived discrimination, optimism, social support, symptoms of trait anxiety, and physical and mental health-related quality of life. Path analysis indicated direct, negative associations between perceived discrimination and both forms of health-related quality of life. Results also showed that these relationships were partially mediated by the reserve capacity variable of optimism and by symptoms of anxiety, though evidence for mediation by anxiety was stronger than for optimism. Findings suggest that perceived discrimination depletes intrapersonal reserves in Hispanic Americans, which, in turn, induces negative emotions. Implications for community-level interventions are discussed.     

Common and specific dimensions of self-reported anxiety and depression: the BDI-II versus the BDI-IA

The Beck Depression Inventory-II (BDI-II) [Beck, A. T., Steer, R. A. & Brown, G. K. (1996). Manual for Beck Depression Inventory-II. San Antonio, TX: Psychological Corporation.] and Anxiety Inventory (BAI) [Beck, A. T. & Steer, R. A. (1993a). Manual for the Beck Anxiety Inventory. San Antonio, TX: Psychological Corporation.] were administered to 840 outpatients who were diagnosed with various types of psychiatric disorders to determine whether the general symptom compositions and relative amounts of variance of the common and specific dimensions of self-reported anxiety and depression for these instruments would be comparable to those that had been found by Steer et al. [Steer, R. A., Clark, D. A., Beck, A. T. & Ranieri, W. F. (1995). Common and specific dimensions of self-reported anxiety and depression: A replication. Journal of Abnormal Psychology, 104, 542–545.] with the BAI and amended Beck Depression Inventory (BDI-IA) [Beck, A. T. & Steer, R. A. (1993b). Manual for the Beck Depression Inventory. San Antonio, TX: Psychological Corporation.]. A Schmid–Leiman transformation was used with the iterated-principal-factor pattern matrix of the BAI and the BDI-II loadings and indicated that the overall symptom compositions and relative amounts of variance that were explained by the one common and two specific anxiety and depression dimensions were comparable to those previously found with the BDI-IA.     

Testing the associative-link hypothesis in immediate serial recall: Evidence from word frequency and word imageability effects

Two immediate serial recall experiments were conducted to test the associative-link hypothesis (Stuart & Hulme, 2000 Stuart, G. and Hulme, C. 2000. The effects of word co-occurrence on short-term memory: Associative-links in long-term memory affect short-term memory performance. Journal of Experimental Psychology: Learning, Memory, and Cognition, 26: 796–802. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We manipulated interitem association by varying the intralist latent semantic analysis (LSA) cosines in our 7-item study word lists, each of which consists of high- or low-frequency words in Experiment 1 and high- or low-imageability words in Experiment 2. Whether item recall performance was scored by a serial-recall or free-recall criterion, we found main effects of interitem association, word imageability, and word frequency. The effect of interitem association also interacted with the word frequency effect, but not with the word imageability effect. The LSA-cosine×word frequency interaction occurred in the recency, but not primacy, portion of the serial position curve. The present findings set explanatory boundaries for the associative-link hypothesis and we argue that both item- and associative-based mechanisms are necessary to account for the word frequency effect in immediate serial recall.     

Shared structuring resources across domains: double task effects from linguistic processing on the structural integration of pitch sequences

Many studies have reported evidence suggesting that resources involved in linguistic structural processing might be domain-general by demonstrating interference from simultaneously presented non-linguistic stimuli on the processing of sentences (Slevc, Rosenberg, & Patel, 2009 Slevc, L. R., Rosenberg, J. C., & Patel, A. D. (2009). Making psycholinguistics musical: Self-paced reading time evidence for shared processing of linguistic and musical syntax. Psychonomic Bulletin & Review, 16(2), 374–381. doi:10.3758/16.2.374[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). However, the complexity of the analysed linguistic processes often precludes the interpretation of such interference as being based on structural—rather than more general—processing resources (Perruchet & Poulin-Charronnat, 2013 Perruchet, P., & Poulin-Charronnat, B. (2013). Challenging prior evidence for a shared syntactic processor for language and music. Psychonomic Bulletin & Review, 20(2), 310–317. doi:10.3758/s13423-012-0344-5[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We therefore used linguistic structure as a source of interference for another structural processing task, by asking participants to read sentences while processing experimentally manipulated pitch sequences. Half of the sentences contained a segment with either an “out-of-context” sentential violation or a “garden path” unexpectancy. Furthermore, the pitch sequences contained a cluster shift, which did or did not align with the sentential unexpectancies. A two-tone recognition task followed each pitch sequence, providing an index of the strength with which this structural boundary was processed. When a “garden path” unexpectancy (requiring structural reintegration) accompanied the cluster shift, the structural boundary induced by this shift was processed more shallowly. No such effect occurred with non-reintegratable “out-of-context” sentential violations. Furthermore, the discussed interference effect can be isolated from general pitch recognition performance, supporting the interpretation of such interference as being based on overlapping structural processing resources (Kljajevic, 2010 Kljajevic, V. (2010). Is syntactic working memory language specific? Psihologija, 43(1), 85–101. doi:10.2298/PSI1001085K[Crossref], [Web of Science ®] , [Google Scholar]; Patel, 2003 Patel, A. D. (2003). Language, music, syntax and the brain. Nature Neuroscience, 6(7), 674–681. doi: 10.1038/nn1082[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]).     

On the Overuse and Misuse of Mediation Analysis: It May Be a Matter of Timing

Kenny (2008) credited Hyman (1955 Hyman, H. (1955). Survey design and analysis: Principles, cases and procedures. Glencoe, IL: The Free Press. [Google Scholar]) with originally discussing mediation analysis under the name elaboration. Of importance, Hyman's elaboration required a time-ordered relationship among variables, such that the mediator must always intervene in time between the predictor and outcome. However, in the modern discussions of mediation (e.g., Baron & Kenny, 1986 Baron, R., & Kenny, D. A. (1986). The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182. doi:10.1037/0022-3514.51.6.1173[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Preacher & Hayes, 2004 Preacher, K. J., & Hayes, A. F. (2004). SPSS and SAS procedures for estimating indirect effects in simple mediation models. Behavior Research Methods, Instruments, & Computers, 36, 717–731. doi:10.3758/bf03206553[Crossref], [PubMed] , [Google Scholar]), this crucial point about time-ordered relationships appears to be underemphasized. This article shows that by employing a conceptual timing criterion for all mediation analyses, the overuse of this technique can be curbed, and, simultaneously, researchers will understand when mediation analyses are appropriate across the behavioral and medical science literatures.     

Untangling the Debate: The Ethics of Human Enhancement

Human enhancement, in which nanotechnology is expected to play a major role, continues to be a highly contentious ethical debate, with experts on both sides calling it the single most important issue facing science and society in this brave, new century. This paper is a broad introduction to the symposium herein that explores a range of perspectives related to that debate. We will discuss what human enhancement is and its apparent contrast to therapy; and we will begin to tease apart the myriad intertwined issues that arise in the debate: (1) freedom & autonomy, (2) health & safety, (3) fairness & equity, (4) societal disruption, and (5) human dignity.

Retrieval-induced forgetting without competition: Testing the retrieval specificity assumption of the inhibition theory

According to the inhibition theory of forgetting (Anderson, Journal of Memory and Language 49:415–445, 2003; Anderson, Bjork, & Bjork, Psychonomic Bulletin & Review 7:522-530, 2000), retrieval practice on a subset of target items leads to forgetting for the other, nontarget items, due to the fact that these other items interfere during the retrieval process and have to be inhibited in order to resolve the interference. In this account, retrieval-induced forgetting occurs only when competition takes place between target and nontarget items during target item practice, since only in such a case is inhibition of the nontarget items necessary. Strengthening of the target item without active retrieval should not lead to such an impairment. In two experiments, we investigated this assumption by using noncompetitive retrieval during the practice phase. We strengthened the cue–target item association during practice by recall of the category name instead of the target item, and thus eliminated competition between the different item types (as in Anderson et al., Psychonomic Bulletin & Review 7:522-530 2000). In contrast to the expectations of the inhibition theory, retrieval-induced forgetting occurred even without competition, and thus the present study does not support the retrieval specificity assumption.     

Death and Black Diamonds: Meaning,Mortality, and the Meaning Maintenance Model

The Meaning Maintenance Model (MMM; Heine, Proulx, & Vohs, 2006 Heine, S. J., Proulx, T. and Vohs, K. D. 2006. The Meaning Maintenance Model: On the coherence of social motivation. Personality and Social Psychological Review, 10(2): 88–111. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposes that human beings innately and automatically assemble mental representations of expected relations. The sense of global meaning that these relations provide is regularly disrupted by unrelated or unrelatable experiences, which elicit feelings of meaninglessness. People respond to these disruptions by engaging in meaning maintenance to reestablish their sense of symbolic unity. Meaning maintenance often involves the compensatory reaffirmation of alternative meaning structures through a process termed fluid compensation. The MMM proposes a fundamental reinterpretation of the social psychological literature, arguing that meaning maintenance is a general mechanism that underlies a host of diverse psychological motivations, including self-esteem needs, certainty needs, and the need for symbolic immortality. In particular, the MMM stands in contrast to Terror Management Theory in that mortality salience is explained by the MMM to be one of many specific instantiations of threats to meaning that engenders fluid compensation.     

Heuristic Reasoning and the Observer's View: The Influence of Example-Availability on ad-hoc Frequency Judgments in Sport

Drawing upon evidence from broader social psychology, and an illustrative study of frequency-estimation during a simple, sport-specific observe-and-recall task, this paper makes the case for the more thorough investigation of the availability heuristic (Tversky & Kahneman, 1973 Tversky, A. and Kahneman, D. 1973. Availability: A heuristic for judging frequency and probability. Cognitive Psychology, 5: 207–232. [Crossref], [Web of Science ®] , [Google Scholar]) on practical state-of-play reasoning in largely observational sporting activities. It is argued that this evidence particularly substantiates a need for a more robust body of research in two primary domains: (a) the gatekeeping tasks pertinent (and usually preliminary) to an individual's sporting performance such as talent scouting, team selection, and substitution decisions, and (b) the business of officiating in high-tempo environments.     

Gender-related inequalities in the division of family work in close relationships: A social psychological perspective

We offer a social psychological perspective on gender-related inequalities in close relationships and integrate two lines of research that have focused on the intrapersonal perceptions and interpersonal consequences respectively of the gendered division of labour. We start with a brief summary of research on gender-related inequalities in the division of labour and discuss prior explanations and paradigms. We then address the extent to which spouses consider the division of labour as fair and the factors that contribute to perceptions of (un)fairness. Central to our argument is the distributive justice framework (<citeref rid="b76">Major, 1987</citeref>, <citeref rid="b77">1993</citeref>; <citeref rid="b113">Thompson, 1991</citeref>) which claims that fairness judgements are affected by people's wants and values, comparison standards, and justifications. In the following section, we address the question of whether dissatisfaction over the division of labour causes relationship conflict and how couples manage these conflicts. The main argument is that conflict over the division of labour generally comprises an asymmetrical conflict structure (with wives as complainants and husbands as defenders of the status quo), which elicits asymmetrical conflict interaction patterns (i.e., demand/withdraw interaction) that result in asymmetrical outcomes (i.e., status quo maintenance). Finally, we summarise the main conclusions and address contributions to theory and research as well as directions for further research.     

Familiar and unfamiliar face recognition: A review

Since the 1970s there has been a continuing interest in how people recognise familiar faces (Bruce, 1979 Bruce, V. 1979. Searching for politicians: An information processing approach to face recognition. Quarterly Journal of Experimental Psychology, 31: 373–395. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; Ellis, 1975 Ellis, H.D. 1975. Recognising faces. British Journal of Psychology, 66: 409–426. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). This work has complemented investigations of how unfamiliar faces are processed and the findings from these two strands of research have given rise to accounts that propose qualitatively different forms of representation for familiar and unfamiliar faces. Evidence to suggest that we process familiar and unfamiliar faces in different ways is available from cognitive neuropsychology, brain scanning, and psychophysics. However, in this review we focus on the evidence, available from experimental investigations of how people recognise faces, for different types of representation existing for each type of face. Factors affecting recognition are evaluated in terms of how they apply to familiar and unfamiliar faces and categorised according to the nature of their impact. In the final section this evidence, along with recent advances in the field, is used to explore the way in which unfamiliar faces may become familiar and the factors that may be important for the development of familiar face representations.
