An investigation of the sexist application of the morality concept of Tsika in the Shona culture of Zimbabwe

We investigated the sexist application of a morality concept of Tsika, characterized by communal traits, in the Shona culture of Zimbabwe. Tsika has been defined as “politeness, civility and circumlocution” (Samkange & Samkange, 1980, p. 74), thus generally falling under communal traits. Theoretical literature suggests that although Tsika is a cultural ideal for all Shona people, it is especially expected of women and children, and that women can be punished like children if they lack Tsika. This research tested whether Tsika would be expected more of women (and children) than men. In line with ambivalent sexism theory, it was predicted that, because Tsika is constituted of communal traits, a bias in its expectation of women over men would be predicted by benevolent sexism. Furthermore, the research tested whether women (and children) would be judged more negatively than men if they defaulted on Tsika. It was hypothesized that a more negative evaluation of women than men if they defaulted on Tsika would be predicted by hostile sexism. Results confirmed that Tsika is expected more of women than of men. Benevolent sexism and its interaction with hostile sexism predicted the bias in expectation of Tsika of women over men. Results also confirmed that women who default on Tsika are evaluated more negatively than men. Hostile sexism predicted the bias in negative evaluations of women over men who default on Tsika.     

A note on the expected value of the Rand index

Two expectations of the adjusted Rand index (ARI) are compared. It is shown that the expectation derived by Morey and Agresti (1984, Educational and Psychological Measurement, 44, 33) under the multinomial distribution to approximate the exact expectation from the hypergeometric distribution (Hubert & Arabie, 1985, Journal of Classification, 2, 193) provides a poor approximation, and, in some cases, the difference between the two expectations can increase with the sample size. Proofs concerning the minimum and maximum difference between the two expectations are provided, and it is shown through simulation that the ARI can differ significantly depending on which expectation is used. Furthermore, when compared in a hypothesis testing framework, multinomial approximation overly favours the null hypothesis.     

The adaptation of the Affective Norms for English Words (ANEW) for European Portuguese

This study presents the adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999a) for European Portuguese (EP). The EP adaptation of the ANEW was based on the affective ratings made by 958 college students who were EP native speakers. Subjects assessed about 60 words by considering the affective dimensions of valence, arousal, and dominance, using the Self-Assessment Manikin (SAM) in either a paper-and-pencil or a Web survey procedure. Results of the adaptation of the ANEW for EP are presented. Furthermore, the differences between EP, American (Bradley & Lang, 1999a), and Spanish (Redondo, Fraga, Padrón, & Comesa?a, Behavior Research Methods, 39, 600–605, 2007) standardizations were explored. Results showed that the ANEW words were understood in a similar way by EP, American, and Spanish subjects, although some sex and cross-cultural differences were observed. The EP adaptation of the ANEW is shown to be a valid and useful tool that will allow researchers to control and/or manipulate the affective properties of stimuli, as well as to develop cross-linguistic studies. The normative values of EP adaptation of the ANEW can be downloaded at .     

The effects of perceptual load on semantic processing under inattention

Inattentional blindness refers to a failure to consciously detect an irrelevant object that appears without any expectation when attention is engaged with another task. The perceptual load theory predicts that task-irrelevant stimuli will reach awareness only when the primary task is of low load, which allows processing resources to spill over to processing task-irrelevant stimuli as well. We studied whether perceptual load has an effect on inattentional blindness for a task-irrelevant stimulus whose meaning is or is not relevant to the attentional goals of the observer. In the critical trial, a word appeared without any expectation in the center of a display of attended pictures. The results showed that, under both high and low load, unexpected words belonging to the attended semantic category were detected more often than semantically unrelated words. These results imply that task-irrelevant stimuli, whose meanings are relevant to the observer’s task, enter awareness irrespective of perceptual load.     

Control of Trajectory Modifications in Target-Directed Reaching

Human reaching movements to fixed and displaced visual targets were recorded and compared with simulated movements generated by using a two-joint arm model based on the equilibrium-point (EP) hypothesis (λ model) of motor control (Feldman, 1986). The aim was to investigate the form of central control signals underlying these movements. According to this hypothesis, movements result from changes in control variables that shift the equilibrium position (EP) of the arm. At any time, muscle activations and forces will depend on the difference between the arm's EP and its actual position and on the limb's velocity. In this article, we suggest that the direction of EP shift in reaching is specified at the hand level, whereas the rate of EP shift may be specified at the hand or joint level. A common mechanism underlying reaching to fixed and displaced targets is proposed whereby the EP of the hand shifts in a straight line toward the present target. After the target is displaced, the direction of the hand EP shift is modified toward the second target. The results suggest that the rate of shift of the hand EP may be modified for movements in different parts of the work space. The model, with control signals that vary in a simple fashion over time, is able to generate the kinematic patterns observed empirically.     

Bifactor Modeling and the Estimation of Model-Based Reliability in the WAIS-IV

Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale–Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet been examined for the WAIS-IV is the bifactor model. Bifactor models allow all subtests to load onto both the general factor and their respective index factor directly. Bifactor models are also particularly amenable to the estimation of model-based reliabilities for both global composite scores (ω _h ) and subscale/index scores (ω _s ). Based on the WAIS-IV normative sample correlation matrices, a bifactor model that did not include any index factor cross loadings or correlated residuals was found to be better fitting than the conventional higher order and oblique factor models. Although the ω _h estimate associated with the full scale intelligence quotient (FSIQ) scores was respectably high (.86), the ω _s estimates associated with the WAIS-IV index scores were very low (.13 to .47). The results are interpreted in the context of the benefits of a bifactor modeling approach. Additionally, in light of the very low levels of unique internal consistency reliabilities associated with the index scores, it is contended that clinical index score interpretations are probably not justifiable.     

Sex differences in social representations of aggression: Men justify,women excuse?

Women tend to hold an expressive social representation of aggression (as a loss of self‐control) while men tend to hold an instrumental representation (as a means of imposing control over others). Because expressive beliefs correspond to excuses and instrumental beliefs to justifications, it may be a sex difference in moral acceptability of aggression that informs social representation. Participants completed the Expagg questionnaire with reference to an episode of same‐sex or cross‐sex physical aggression and rated the moral acceptability of their behaviour. Women scored higher on Expagg (specifically lower than men on the instrumental scale) but there was no effect of target sex or participant‐by‐target interaction. Contrary to expectation, women rated their own aggression as more acceptable than did men and hence this could not explain their lower levels of instrumentality relative to men. Aggr.

Classifying retrieval strategies as a function of working memory

Strategy selection may help explain performance differences between individuals with high working memory capacity (HWMs) and low working memory capacity (LWMs) (Budd, Whitney, & Turley, (Memory & Cognition, 23, 735–748 1995); Cokely, Kelley, & Gilchrist, (Psychonomic Bulletin & Review, 13, 991–997 2006). We compared the independent and spontaneous strategy use of HWMs and LWMs during a category fluency (retrieval) task that required participants to retrieve animal names. HWMs were more successful at the fluency task under normal conditions, but under increased cognitive load, there were no WM-related performance differences. One strategy (i.e., retrieving animals according to their scientific classification) significantly aided performance, irrespective of cognitive load. Under normal conditions, HWMs were more likely to use the effective strategy; however, under load, WM did not predict strategy use. Use of the classification strategy was more strongly related to retrieval performance than was WM. These results suggest that retrieval strategy use is related to WM capacity, and that employing a successful strategy may make up for WM disadvantages during a demanding retrieval task.     

Being different or being better? National stereotypes and identifications of Polish and Dutch students

This paper investigates two theoretical statements that are central to Social Identity Theory and Self-Categorization Theory: (1) when people identify as members of a social group, they are motivated to distinguish this group in a positive sense from relevant comparison groups, and: (2) in an hierarchically organized system of possible social identities, people may define their identity at various levels, but two levels cannot be salient in the same situation. Four studies investigate whether these hypothesized processes can be traced in natural social categories. Study 1 (N=150) found that Polish subjects had a more negative national stereotype than Dutch subjects. Study 2 (N=160) investigated whether these national stereotypes were related to the perceived distinctiveness of national traits, and to differential levels of national and European identification for Polish and Dutch subjects. Contrary to the expectations, it was found that Polish subjects identified more strongly with their national group than Dutch subjects. Both positive and negative national traits were considered more distinctive by Polish subjects than by Dutch subjects. Moreoever, Polish subjects expressed stronger European identity than Dutch subjects. Study 3 (N=161) replicated the findings of Study 2 under more controlled conditions. The Polish national stereotype was found to be largely based on negatively evaluated traits, and Polish subjects were more motivated to accentuate the distinctiveness of their national traits than Dutch subjects. Again, Polish subjects displayed stronger national and European identities. Further-more, no support was found for the expectation that Polish subjects would employ some self-protective strategy when such an opportunity was offered in this study. Similarly, in Study 4 (N=40) we found no evidence that Polish subjects utilized an alternative self-protective mechanism, namely ‘group-serving’ attributions, by means of which negative national traits could be ascribed to external circumstances. The results of these four studies are discussed in relation to Social Identity Theory, Self-Categorization Theory and political/historical developments in Europe.     

Gain–loss-frame in outcome-interdependence: does it influence equality or equity considerations?

Research suggests that framing outcomes as gains produces stronger concern for distributive justice than framing outcomes as losses. Unfortunately, however, this prior research manipulated own and other's outcomes only (and not own and other's input). Hence, it remained unclear whether framing affects concern with equality—everyone gets an equal share regardless whether one ‘deserves’ it or not—and/or equity—the share one gets is a function of the proportionality of one's own, and the other parties' inputs. The current experiment addressed this problem. Subjects (N = 94) read a scenario manipulating own and some co-workers' inputs, and subsequently rated satisfaction with pairs of outcomes providing themselves with more, equal or less outcomes than their co-worker. Outcomes to oneself exceeded expectation (gain-frame) or remained below it (loss-frame). Corroborating and expanding prior research, results showed that people are more concerned with both equality and equity when they have a gain- rather than loss-frame. In addition, results revealed evidence for a self-serving bias, in that people prefer equity or equality, depending on what serves best their own interests. It is concluded that frame affects the degree to which people are concerned about distributive justice.     

Attentional sets influence perceptual load effects,but not dilution effects

Perceptual load theory [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–468.; Lavie, N., & Tsal, Y. (1994) Perceptual load as a major determinant of the locus of selection in visual attention. Perception & Psychophysics, 56, 183–197.] proposes that interference from distractors can only be avoided in situations of high perceptual load. This theory has been supported by blocked design manipulations separating low load (when the target appears alone) and high load (when the target is embedded among neutral letters). Tsal and Benoni [(2010a). Diluting the burden of load: Perceptual load effects are simply dilution effects. Journal of Experimental Psychology: Human Perception and Performance, 36, 1645–1656.; Benoni, H., & Tsal, Y. (2010). Where have we gone wrong? Perceptual load does not affect selective attention. Vision Research, 50, 1292–1298.] have recently shown that these manipulations confound perceptual load with “dilution” (the mere presence of additional heterogeneous items in high-load situations). Theeuwes, Kramer, and Belopolsky [(2004). Attentional set interacts with perceptual load in visual search. Psychonomic Bulletin & Review, 11, 697–702.] independently questioned load theory by suggesting that attentional sets might also affect distractor interference. When high load and low load were intermixed, and participants could not prepare for the presentation that followed, both the low-load and high-load trials showed distractor interference. This result may also challenge the dilution account, which proposes a stimulus-driven mechanism. In the current study, we presented subjects with both fixed and mixed blocks, including a mix of dilution trials with low-load trials and with high-load trials. We thus separated the effect of dilution from load and tested the influence of attentional sets on each component. The results revealed that whereas perceptual load effects are influenced by attentional sets, the dilution component is not. This strengthens the notion that dilution is a stimulus-driven mechanism, which enables effective selectivity.     

The Effect of modality specific interference on working memory in recalling aversive auditory and visual memories*

Both auditory and visual emotional memories can be made less emotional by loading working memory (WM) during memory recall. Taxing WM during recall can be modality specific (giving an auditory [visuospatial] load during recall of an auditory [visual] memory) or cross modal (an auditory load during visual recall or vice versa). We tested whether modality specific loading taxes WM to a larger extent than cross modal loading. Ninety-six participants undertook a visual and auditory baseline Random Interval Repetition task (i.e. responding as fast as possible to a visual or auditory stimulus by pressing a button). Then, participants recalled a distressing visual and auditory memory, while performing the same visual and auditory Random Interval Repetition task. Increased reaction times (compared to baseline) were indicative of WM loading. Using Bayesian statistics, we compared five models in terms of general and modality specific taxation. There was support for the model describing the effect on WM of dual tasking in general, irrespective of modality specificity, and for the model describing the effect of modality specific loading. Both models combined gained the most support. The results suggest a general effect of dual tasking on taxing WM and a superimposed effect of taxing in matched modality.     

A contextual approach on sex-related biases in pain judgements: The moderator effects of evidence of pathology and patients’ distress cues on nurses’ judgements of chronic low-back pain

Although women report feeling more pain than men, their pain is often underdiagnosed and undertreated. By proposing a gender-based theoretical conceptualisation, we argue that such sex-related biases may be enhanced or suppressed by contextual variables pertaining to the clinical situation, the perceiver or the patient. Consequently, we aimed to explore the moderator role of two clinically relevant variables in a chronic low-back pain (CLBP) scenario: diagnostic evidence of pathology (EP) and pain behaviours conveying distress. One-hundred and twenty-six female nurses (M?=?35.33, SD?=?7.64) participated in an experimental between-subjects design, 2 (patient's sex)?×?2 (EP: present vs. absent)?×?2 (pain behaviours: with vs. without distress). Independent variables were operationalised by vignettes depicting a patient with CLBP. Nurses judged the patient's pain on several dimensions: (1) credibility; (2) disability; (3) severity of the clinical situation; (4) psychological attributions and (5) willingness to offer support. Main findings showed that judgements of women's pain were influenced by EP, while judgements of men's pain were not. Moreover, nurses showed biases against men, but only in the presence of EP. The influence of distress cues was less consistent. Theoretical and practical implications are drawn.     

The Analytic Truth and Falsity of Disjunctions

Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus.     

Constructing We‐ness: A Communal Coping Intervention for Couples Facing Chronic Illness

Communal coping occurs when relationship partners view a stressful health problem as “ours,” rather than yours or mine, and take collaborative action to deal with it. Although research employing linguistic (we‐talk) and other measures of communal coping demonstrates relevance to a variety of chronic illnesses, the literature offers little about how clinicians can actively promote we‐ness and teamwork to help patients and their partners achieve the health benefits this appears to confer. This paper highlights clinical and supporting scientific features of a narrative intervention designed to foster communal coping by couples in which one partner has a chronic illness. The illustrative illness is diabetes, but with modification the protocol is suitable for other chronic conditions as well. Grounded in systemic and narrative models of problem maintenance and change, the communal coping intervention represents a distillation of research and clinical experience with family consultation over several decades. In contrast to more directive and educational approaches, the intervention consists entirely of questions, with no direct suggestions or instruction about how patients, partners, or couples should change. These questions comprise 8 sequential modules (Coping Challenges, Trajectory and Focus, Illness as External Invader, You as a Couple, Past Teamwork in Overcoming Adversity, Present and Future Teamwork, Obstacles to Teamwork, and Wrap‐Up), described here in manual‐like detail.     

Pitches that Wire Together Fire Together: Scale Degree Associations Across Time Predict Melodic Expectations

The ongoing generation of expectations is fundamental to listeners’ experience of music, but research into types of statistical information that listeners extract from musical melodies has tended to emphasize transition probabilities and n-grams, with limited consideration given to other types of statistical learning that may be relevant. Temporal associations between scale degrees represent a different type of information present in musical melodies that can be learned from musical corpora using expectation networks, a computationally simple method based on activation and decay. Expectation networks infer the expectation of encountering one scale degree followed in the near (but not necessarily immediate) future by another given scale degree, with previous work suggesting that scale degree associations learned by expectation networks better predict listener ratings of pitch similarity than transition probabilities. The current work outlines how these learned scale degree associations can be combined to predict melodic continuations and tests the resulting predictions on a dataset of listener responses to a musical cloze task previously used to compare two other models of melodic expectation, a variable-order Markov model (IDyOM) and Temperley's music-theoretically motivated model. Under multinomial logistic regression, all three models explain significant unique variance in human melodic expectations, with coefficient estimates highest for expectation networks. These results suggest that generalized scale degree associations informed by both adjacent and nonadjacent relationships between melodic notes influence listeners’ melodic predictions above and beyond n-gram context, highlighting the need to consider a broader range of statistical learning processes that may underlie listeners’ expectations for upcoming musical events.     

The verifiability approach to deception detection: A preregistered direct replication of the information protocol condition of Nahari,Vrij, and Fisher (2014b)

Nahari, Vrij, and Fischer [(2014b), Applied Cognitive Psychology, 28, 122–128] found that, when participants were forewarned that their statements would be checked for verifiable details, truth tellers gave much more verifiable details than liars. In this direct replication (n = 72), participants wrote a statement claiming they had carried out their regular campus activities, whereas liars had actually stolen an exam. Statements were coded for verifiable details. Our primary prediction was confirmed: Truth tellers provided significantly more verifiable details than liars. Of note, the replication effect size (d = 0.49) was less than half that of the original (d = 1.14), and – like in the original study – was smaller than the lie‐truth effect size for total details (verifiable and unverifiable details combined; d = 0.80). We hope this will stimulate other independent investigations of VA to tell whether or not coding for verifiability will pass Ockham's razor test.     

Quadratic prediction of factor scores

Factor scores are naturally predicted by means of their conditional expectation given the indicatorsy. Under normality this expectation is linear iny but in general it is an unknown function ofy. It is discussed that under nonnormality factor scores can be more precisely predicted by a quadratic function ofy.The authors would like to thank Edith Nijenhuis, the anonymous referees, and the associate editor for their helpful comments and suggestions.     

Facilitating Internalization: The Self-Determination Theory Perspective

Self-determination theory (Deci & Ryan, 1985) posits that (a) people are inherently motivated to internalize the regulation of uninteresting though important activities; (b) there are two different processes through which such internalization can occur, resulting in qualitatively different styles of self-regulation; and (c) the social context influences which internalization process and regulatory style occur. The two types of internalization are introjection, which entails taking in a value or regulatory process but not accepting it as one's own, and integration, through which the regulation is assimilated with one's core sense of self. Introjection results in internally controlling regulation, whereas integration results in self-determination. An experiment supported our hypothesis that three facilitating contextual factors—namely, providing a meaningful rationale, acknowledging the behaver's feelings, and conveying choice—promote internalization, as evidenced by the subsequent self-regulation of behavior. This experiment also supported our expectation that when the social context supports self-determination, integration tends to occur, whereas when the context does not support self-determination, introjection tends to occur.     

Rationality and Synchronic Identity

Many requirements of rationality rely for their application on facts about identity at a time. Take the requirement not to have contradictory beliefs. It is irrational if a single agent believes P and believes ～P, but it is not irrational if one agent believes P and another believes ～P. There are puzzle cases, however, in which it is unclear whether we have a single agent, or instead two or more. I consider and reject possible criteria of identity at a time before proposing a pluralist alternative on which there are vastly more agents than we might have thought. This pluralist thesis is analogous to mereological universalism, on which there are all sorts of strange disconnected objects of which we don’t usually take note. I conclude by giving a pragmatic account of which of these rational agents it makes sense to attend to, by appealing the purposes that we have in employing rationally evaluative language.
