Do age-related differences in episodic feeling of knowing accuracy depend on the timing of the judgement?

The current study investigated whether there were age-related differences in episodic feeling-of-knowing (FOK) accuracy and whether accuracy was influenced by when the FOK judgements were made. Younger and older participants were randomly assigned to one of four conditions that manipulated the timing of the FOK in relation to cued recall and associative recognition. Age-related differences in FOK accuracy were not reliable either when the FOK was immediate or when it was delayed. Moreover, FOK accuracy was above chance for both age groups. Remember/Know (RK) judgements correlated reliably with FOKs for unrecalled words for both age groups and did not vary by FOK timing. The invariance in FOK accuracy occurred despite robust age differences in associative cued recall and associative recognition, as well as age differences in recollection as measured by RK judgements. The findings are inconsistent with the argument that there is a general age deficit in episodic FOK accuracy. Possible reasons for discrepant findings in the literature are discussed.     

Does the justice of the one interact with the justice of the many? Reactions to procedural justice in teams

This article reported the results of 2 studies that examined reactions to procedural justice in teams. Both studies predicted that individual members' reactions would be driven not just by their own procedural justice levels but also by the justice experienced by other team members. Study 1 examined intact student teams, whereas Study 2 occurred in a laboratory setting. The results showed that individual members' own justice interacted with others' justice, such that higher levels of role performance occurred when justice was consistent within the team. These effects were strongest in highly interdependent teams and weakest for members who were benevolent with respect to equity sensitivity.     

On the process of recognizing inverted words: Does it rely only on orientation-invariant cues?

Following a demonstration by Parks (1983) of failure to notice the reflection of a letter of an inverted word, two experiments were conducted to test a hypothesis about the process of recognizing inverted words that is termed here invariant cues only (ICO)-a letter-by-letter identification process based only on orientation-invariant letter features. In Experiment 1, subjects were presented with whole strings-words and nonwords, either upright or inverted-in which either all the letters were normal or one of the letters was reflected, and they were asked to make lexical decisions. In Experiment 2, subjects made a reflection judgment about an upright or inverted letter within a string immediately after they had been presented with the other, nonreflected string letters, again either upright or inverted. The results do not support the ICO hypothesis: Lexical decisions were greatly affected by the reflection of a letter in upright and inverted stimuli alike. Reflection judgments were considerably facilitated by word context in the upright and the inverted modes alike. The results are accommodated better by the notion that recognition of disoriented words requires some correction used to restore orientation-sensitive features.     

Does the testing effect depend on presentation modality?

We examined whether the testing effect generalizes to an auditory presentation modality. Five lists of unrelated words (Experiment 1) and related words (Experiment 2) were presented to participants, half of whom studied them visually and half studied them auditorily. Participants in the study-only condition performed a short distractor task following lists 1–4, whereas those in the testing condition completed a short distractor task and then attempted to recall each list. Both groups were subsequently tested on List 5 and on all five lists 30 min later. In both experiments, we found a testing effect for both List 5 and for the final cumulative recall test. However, the effect did not interact with study modality, despite the fact that proactive interference was greater following auditory study. These results have important implications for educational practice, suggesting that initial testing is important for materials presented in auditory as well as visual formats.     

Does response interference depend on the subjective visibility of flanker distractors?

Response interference (or response conflict) refers to the phenomenon whereby response times to a target stimulus are longer in the presence of distractor stimuli that indicate contrary motor responses. Response interference has been observed even when the distractor stimuli cannot be discriminated above chance levels. These results raise the question of whether response interference might be driven automatically by the physical distractor stimuli, independently of one??s subjective perception of the distractors. Using a modified version of the Eriksen flanker task, we applied metacontrast masks to the flanker stimuli and measured their subjective visibility after each trial. We found converging lines of evidence that the subjective perception of flankers contributed to response interference, over and above the contribution of automatic processing of the stimulus itself. A factorial analysis revealed that the objective, physical congruency of target and flankers and the subjective, perceptual congruency of target and flankers make additive, noninteracting contributions to target response interference, suggesting that the two interference effects originate from independent levels or stages of cognitive processing.     

Does the mortality salience effect on worldview defence depend on the cultural orientation of Chinese people?

According to the terror management theory, people tend to favour their worldview and in-group members after being reminded of death (i.e., mortality salience [MS] effect). However, inconsistent findings of the MS effect were found among Chinese people. In the present study, we examined the MS effect with Chinese samples and tested whether the effect would depend on participants' cultural orientation and relational self-esteem. In Studies 1 (N = 227) and 2 (N = 221), we examined the roles of participants' cultural orientations and relational self-esteem in their evaluations on moral transgression and/or perceived regard from people around after being primed with mortality (vs. dental pain) salience. We obtained the interaction effects of mortality salience, cultural orientations, and relational self-esteem. The implications of these results are discussed in the context of Chinese culture.     

Do sex differences in a faceted model of fluid and crystallized intelligence depend on the method applied?

Recently, different methodological approaches have been discussed as an explanation for inconsistencies in studies investigating sex differences in different intelligences. The present study investigates sex differences in manifest sum scores, factor score estimates, and latent verbal, numerical, figural intelligence, as well as fluid and crystallized intelligence as measured by the German Intelligence-Structure-Test 2000-R (IST 2000-R; Liepmann, Beauducel, Brocke, & Amthauer, 2007). The not population-representative sample consisted of 977 German 11th and 12th graders enrolled in a “Gymnasium” (551 female; mean age: M = 16.70; SD = 0.65) who completed the IST 2000-R. Sex differences in fluid and crystallized intelligence were not influenced by the method applied with men performing better than women. However, extent and direction of sex differences in verbal, numerical, and figural intelligence differed by the method applied. Whereas there was a male advantage in all three factors measured as manifest sum scores, women performed better in verbal intelligence as measured by factor scores or as latent variables. Effect sizes of sex differences in numerical and figural intelligence were also greatly reduced when applying the latter two methods. Results are discussed with regard to their theoretical and practical implications.     

Does implicit learning in non-demented Parkinson’s disease depend on the level of cognitive functioning?

We investigated the influence of the level of cognitive functioning on sequence-specific learning in Parkinson's disease (PD). This was done by examining the relationship between the scales for outcomes in Parkinson's disease-cognition [SCOPA-COG, Marinus, J., Visser, M., Verwey, N. A., Verhey, F. R. J., Middelkoop, H. A. M.,Stiggelbout, A., et al. (2003). Assessment of cognition in Parkinson's disease. Neurology, 61, 1222-1228] and the serial reaction time (SRT) task [Nissen, M. J., & Bullemer, P. T. (1987). Attentional requirements for learning: Evidence from performance measures. Cognitive Psychology, 19, 1-32] in a homogeneous sample, consisting of 25 PD patients diagnosed in Stage 3 of the Hoehn and Yahr [Hoehn, M. M., & Yahr, M. D. (1967). Parkinsonism: onset, progression, and mortality. Neurology, 17, 427-442] scale. Six patients in the low scoring cognitive group, 11 patients in the average scoring and eight patients in the high scoring group, conducted a SRT task with a deterministic sequence. Sequence-specific learning was assessed by inserting a random block to determine whether the acquisition of sequence movements differed between groups. Our results indicate an association between cognitive functioning in PD patients and sequence learning. These findings emphasize the use of assessing cognition in addition to the well-known motor aspects in PD.     

Does the direction and magnitude of cognitive change depend on initial level of ability?

Longitudinal change in five cognitive abilities was investigated to determine if the direction or magnitude of change was related to the individual's ability level. Adults between 18 and 97 years of age performed three versions of 16 cognitive tests on two occasions separated by an average of 2.7 years. In order to control for influences associated with regression toward the mean, level of ability was determined from scores on the first version of the cognitive tests on the first occasion, and across-occasion change was examined on the second and third versions. Change in every cognitive ability was significantly more negative with increased age. However, there was little indication of ability-dependent change in any of the five cognitive abilities, either in differences between composite scores, or in estimates of latent change. Although there are reasons to expect cognitive change to be less negative at either high or low levels of ability, these data suggest that neither the direction nor magnitude of change is related to initial ability when influences of regression toward the mean are controlled.     

Is the debate on ‘global justice’ a global one? Some considerations in view of modern philosophy in Africa

At present, the debate on global justice, a debate which is at the core of global ethics, is largely being conducted by European and American scholars from different disciplines without taking into account views and concepts from other regions of the world, particularly, from the Global South. The lack of a truly intercultural, interreligious, and international exchange of ideas provokes doubts whether the concepts of global justice introduced so far are able to transcend regional and cultural horizons. The article introduces concepts of justice from African scholars, whose voices have remained marginal until now, like the Kenyan philosopher Henry Odera Oruka, the Ethiopian philosopher Teodros Kiros, and the debate on ubuntu, one of the most controversial concepts in southern Africa today. These concepts focus on issues that are seldom considered in the debate on global justice, such as the importance of bodily needs as a prerequisite for human beings to act as moral beings and the importance of human relationships and solidarity. The last part of the article discusses factors which lead to exclusion from the academic discourse and the question how we as scholars can work for more academic justice.     

Does sensitivity in binary choice tasks depend on response modality?

In most models of vision, a stimulus is processed in a series of dedicated visual areas, leading to categorization of this stimulus, and possible decision, which subsequently may be mapped onto a motor-response. In these models, stimulus processing is thought to be independent of the response modality. However, in theories of event coding, common coding, and sensorimotor contingency, stimuli may be very specifically mapped onto certain motor-responses. Here, we compared performance in a shape localization task and used three different response modalities: manual, saccadic, and verbal. Meta-contrast masking was employed at various inter-stimulus intervals (ISI) to manipulate target visibility. Although we found major differences in reaction times for the three response modalities, accuracy remained at the same level for each response modality (and all ISIs). Our results support the view that stimulus-response (S-R) associations exist only for specific instances, such as reflexes or skills, but not for arbitrary S-R pairings.     

Does retrieval practice depend on semantic cues? Assessing the fuzzy trace account of the testing effect

Retrieval practice enhances long-term retention more than restudying; a phenomenon called the testing effect. The fuzzy trace explanation predicts that a testing effect will already emerge after a short interval when participants are solely provided with semantic cues in the final test. In the present study, we assessed this explanation by gradually reducing the surface features overlap between cues in the learning phase and the final recognition test. In all five experiments, participants in the control/word condition received as final test cues the same words as in the learning phase. The experimental final test cues consisted of scrambled words, words in a new context, scrambled words in a new context (Experiment 1), synonyms (Experiment 2), or images (Experiments 3, 4a, 4b). A short-term testing effect was only observed for the image final test cues. These results do not provide strong support for the fuzzy trace explanation of the testing effect.     

In Cinderella's slippers? Story comprehension from the protagonist's point of view

Research on text comprehension shows that readers construct a model of the situation described in a narrative. A major factor in constructing a situational model is the perspective from which the action of the narrative is imagined. J. B. Black, T. J. Turner, and G. H. Bower (1979) found that adults recall a deictic verb of motion more accurately if it is spatially consistent with the point of view of the main protagonist. Recall is more accurate for the verbs come and bring if they describe a movement toward the protagonist; recall is more accurate for go and take if they describe a movement away from the protagonist. Thus, adults interpret movements in a narrative from the perspective of the protagonist. This study indicates that 3- and 4-year-old children show the same pattern of recall. They accurately recall verbs of motion that are consistent with the protagonist's perspective but make substitution errors on verbs inconsistent with that perspective.     

Does grasping in patient D.F. depend on vision?

A recently published study of grasping in patient D.F. challenges the well-known dissociation between vision-for-perception and vision-for-action, suggesting instead that D.F.'s preserved grip scaling depends entirely on haptic feedback. We argue that the results of the study are in fact fully consistent with the perception-action account.     

Evolved sex differences in the number of partners desired? The long and the short of it

Do men seek more short-term mates than women? Buss and Schmitt (1993) showed a pattern of mean difference in the ideal number of sexual partners men and women desired over various time frames. We replicated these mean sex differences (e.g., ideal number over the next 30 years: Ms = 7.69 and 2.78 for men and women, respectively), but in both data sets the sampling distributions were highly skewed. In Study 1, we found few sex differences in medians across time frames (e.g., ideal number over the next 30 years: Mdn = 1 for both men and women). In Study 2, most college men (98.9%) and women (99.2%) said they wanted to settle down with one mutually exclusive sexual partner at some point in their life, ideally within the next 5 years. Neither medians in number of partners desired overall before settling down (replicating Study 1) nor medians in short-term partners desired before settling down (Mdn = 0) differed significantly by gender. Rather, men and women concurred: Short-term mating is not what humans typically seek.     

Is it advisable to include negative attributes to assess the stereotype content? Yes,but only in the morality dimension

Competence, morality and sociability dimensions have shown to be essential to measure stereotypes. Theoretically, the attributes associated with the negative pole of morality are more reliable and have shown to have higher evaluative weight. However, the current research usually employs only positive attributes to measure each dimension. Since the advantages of the inclusion of negative morality are clear it would be interesting to know about the effects of the inclusion of such type of attributes (i.e., it is good or bad for the measurement). The purpose of this study is to examine if the addition of negative items makes possible to improve the stereotype content measures. This study compares the differences between scales with various compositions of positive and negative items of stereotypes to predict three related variables: anger, fear and a semantic differential of evaluation. The study was carried out with a sample of 550 Spaniards. The data found highlights the importance of using attributes of the negative pole of morality in studying stereotypes. Their use was able to explain the intergroup emotional responses and the semantic differential more efficiently.     

Does making a conversation asynchronous reduce the negative impact of phone call on driving?

Mobile phone use at the wheel has a proven negative impact on driving. This paper aims to assess whether using an answerphone instead of a normal phone reduces this negative impact. The answerphone makes communication asynchronous and splits it into three disconnected and successive phases: interaction with the voice interface, listening to the message and answering, which have been evaluated separately.The experiment was conducted on a fixed base simulator, with 30 participants (half male and female, aged from 18 to 50 years, driving at least 5000 km per year).The results show better scores for correct responses to stimuli for answerphone communications than for phone communications, although response times were higher in both communication conditions than in the driving alone condition. When the three phases of answerphone use were compared, interacting with the answerphone and listening to the message were found to be significantly less disturbing than answering, in terms of correct responses and response times.By making the conversation asynchronous, the answerphone avoids direct interaction between driver and caller. The fact that communication is under the driver’s control allows him/her to pace the interaction better. Lastly, splitting up the conversation into different phases decreases the overall task difficulty.
