What does doodling do?

Doodling is a way of passing the time when bored by a lecture or telephone call. Does it improve or hinder attention to the primary task? To answer this question, 40 participants monitored a monotonous mock telephone message for the names of people coming to a party. Half of the group was randomly assigned to a ‘doodling’ condition where they shaded printed shapes while listening to the telephone call. The doodling group performed better on the monitoring task and recalled 29% more information on a surprise memory test. Unlike many dual task situations, doodling while working can be beneficial. Future research could test whether doodling aids cognitive performance by reducing daydreaming. Copyright © 2009 John Wiley & Sons, Ltd.     

Why does picture naming take longer than word reading? The contribution of articulatory processes

Since the 19th century, it has been known that response latencies are longer for naming pictures than for reading words aloud. While several interpretations have been proposed, a common general assumption is that this difference stems from cognitive word-selection processes and not from articulatory processes. Here we show that, contrary to this widely accepted view, articulatory processes are also affected by the task performed. To demonstrate this, we used a procedure that to our knowledge had never been used in research on language processing: response-latency fractionating. Along with vocal onsets, we recorded the electromyographic (EMG) activity of facial muscles while participants named pictures or read words aloud. On the basis of these measures, we were able to fractionate the verbal response latencies into two types of time intervals: premotor times (from stimulus presentation to EMG onset), mostly reflecting cognitive processes, and motor times (from EMG onset to vocal onset), related to motor execution processes. We showed that premotor and motor times are both longer in picture naming than in reading, although than in reading, although articulation is already initiated in the latter measure. Future studies based on this new approach should bring valuable clues for a better understanding of the relation between the cognitive and motor processes involved in speech production.     

The combined effects of plane disorientation and foreshortening on picture naming: one manipulation or two?

Objects disoriented in plane away from the upright and objects rotated in depth producing foreshortening are harder to identify than canonical views. In Experiments 1 and 2, participants named pictures of familiar objects. There was no interaction between plane and depth rotation effects on initial presentation or after practice. Experiment 3 was a dual-task psychological refractory period study. Participants classified a high-low tone with a speeded keypress and then named a canonical, plane-rotated, or foreshortened view of an object. Naming was slower when the picture was presented 50 ms after the tone compared with 800 ms after the tone. Plane rotation effects were reduced (but not eliminated) at the short tone-picture stimulus onset asynchrony, but foreshortening effects were not reduced. The results implicate an early, prebottleneck locus for some processes compensating for plane rotation and a subsequent bottleneck or postbottleneck locus for compensation for foreshortening.     

What does rapid automatized naming measure? A new RAN task compared to naming and lexical decision

The present research investigated the relationship between Rapid Automatized Naming (RAN) performance, letter-string reading measures of sight vocabulary (SV) and phonetic decoding (PD), and lexical decision. Criterion-based naming rates were obtained from three types of RAN tasks: digits, letters, and letter sounds. Latency measures were obtained from the naming of regular words, exception words, nonwords and pseudohomophones; as well as button press and verbal lexical decision tasks. Regression analyses supported the hypotheses that RAN-Letters latency reflects SV processing in that its variance is uniquely accounted for by exception word naming latency and button press lexical decision latency, and that RAN-Letter Sounds latency best reflects PD processing in that its variance is uniquely accounted for by pseudohomophone and nonword naming latency. Findings are discussed in light of what the RAN tasks are measuring, implications involving visual word recognition models of reading, and the utility of the new RAN-Letter Sounds task with respect to diagnostic and remediation applications.     

What does being initiated severely into a group do? The role of rewards

Undergoing an admission process (an initiation) can induce exaggerated feelings about a group, but there is little research about the role of rewards. This study replicated Aronson and Mills’ (1959) experiment. Seventy participants underwent either a severe initiation or a mild initiation. After the initiation, about half the sample received an extrinsic reward for merely completing the task. The remaining half did not receive an extrinsic reward. This was to vary the amount of dissonance. Initiation severity and reward condition had significant, noncrossing interactions. A reward led to higher group identity than no reward, supporting Levine and Moreland's (1994) group socialization model. A severe initiation did not lead to more group identity than a mild initiation; therefore, Aronson and Mills’ findings were not replicated. Interestingly, a mild initiation followed by a reward led to more group identity than a severe initiation followed by a reward. Another unexpected finding was that the extrinsic reward made no difference to group identity if the initiation was severe. Effects on ratings of the discussion were nonsignificant. Future research needs to establish how new group members ponder the severity of the admission process during the cost–benefit calculation preceding their identification with a group.     

Do living and nonliving categories need further fractionation? A study of picture naming in a pathological sample

A group of 51 patients affected by possible semantic memory deficit were given a picture naming task for the purposes of a comparison between six categories, three of Nonliving nature (tools, furniture, vehicles) and three of a Living nature (animals, fruits, and vegetables). A logistic regression analysis was used for a multiple single case study, where also the items' basic difficulty was included in the model. Besides some patients showing a dissociation between Living and Nonliving categories, other patients showed a finer selectivity on naming, differentiating animals from fruits and vegetables, tools from nonmanipulable objects, and even vehicles from furniture. These results are examined in the light of current theories of semantic category specificity.     

Stress and cytokine effects on learning: What does sex have to do with it?

Many studies have alluded to sexually dimorphic changes in behavior following stress. Although many have suggested that these changes are a function of stress-induced changes in learning and memory, there are questions regarding whether performance in those learning and memory tasks are influenced by stress-induced changes in drive more than in actual learning and memory processes. We used the classically conditioned eyeblink response (CCER) to determine whether slowed learning following stress in females can be explained by changes in unconditional response (UR) amplitude, a sign of a stress-induced shift in sensory reactivity. In addition, we had a second treatment group injected with the pro-inflammatory cytokine IL-1β to serve as an interoceptive stress condition, a physiological stressor with minimal stimulation to the animal. Replicating the work by Shors and colleagues, we found that stressed female rats had slower acquisition of the conditioned response (CR), but we also found that an IL-1β injection leads to a slowing of CR acquisition. However, in both cases, UR amplitude was lower in the treatment groups. We followed up these results by testing sensory reactivity through the acoustic startle response (ASR), where the magnitude of the ASR was marginally, but nonsignificantly, reduced by the same dose regimen of IL-1β. Together, these experiments suggest that tailshock stress and immune signaling (IL-1β) reduce sensory reactivity and the saliency of the stimuli used in the CCER, leading to slower learning in female rats.     

What mediates the impact of response alternatives on frequency reports of mundane behaviors?

Previous research demonstrated that respondents assume that the range of precoded response alternatives reflects the researcher's knowledge of the distribution of opinions or behaviours in the population. This assumption may influence respondents' reports in two ways: respondents may either use the range of the response alternatives as a frame of reference in estimating their own behavioural frequencies, or they may be reluctant to report frequencies that appear extreme in the context of the scale. Three experiments using reports of mundane behaviours, namely watching TV and drinking beer, were conducted to differentiate between the frame of reference and the self-presentation hypothesis. The results of all studies favour the frame of reference hypothesis, and suggest that the impact of response alternatives is the more pronounced the less episodic information about the behaviour is accessible in memory. Specifically, proxy-reports were found to be more affected by the range of response alternatives than self-reports (Experiments 1 and 2), and respondents with dispositionally low access to self-related information were found to be more affected than respondents with dispositionally high access to self-related information (Experiment 3). Implications for questionnaire construction are discussed.     

What does a man do after he makes an error? an analysis of response programming

When people make errors during continuous tasks they temporarily pause and then slow down. One line of explanation has been that they monitor feedback to detect errors, that they may make incidental responses when errors occur (e.g. they may swear) and that they may pause to analyse their errors. In all these cases they may be assumed to act as single channel information processing systems of limited capacity, and to be unable to recognise any new signal until these processes have been completed.

Analysis of response after errors shows that this cannot be the case. Responses after errors are inaccurate, but are not slow when they require the subject to make the response which he should have made on the previous trial (i.e. to make an error correction response). Subjects thus must recognise new signals as soon as they occur. The present results require a new model of error detection and correction, and a model for response programming and priming.     

What Is a Conventional Object Function? The Effects of Intentionality and Consistency of Use

By preschool age, children have a sophisticated assumption about the conventional nature of various kinds of information. The present studies investigated the role of two cues in 2- and 3-year-olds' determination of what is conventional, namely the intentionality and intra-individual consistency in the use of objects. Overall, in Study 1, both 2- and 3-year-olds were more likely to say that the expected use and purpose of an object was a function intentionally and consistently demonstrated. In Study 2, 3-year-olds but not 2-year-olds generalized their expectation about the conventionality of an intentionally demonstrated function to another agent's learning of the function. These findings shed light on how children's assumption of what is conventional gets refined via children's intuitive interpretive dispositions regarding human actions.     

What do we Want from a Theory of Happiness?

I defend a methodology for theorizing about happiness. I reject three methods: conceptual analysis; scientific naturalism; and the “pure normative adequacy” approach, where the best conception of happiness is the one that best fills a role in moral theory. The concept of happiness is a folk notion employed by laypersons who have various practical interests in the matter, and theories of happiness should respect this fact. I identify four such interests in broad terms and then argue for a set of desiderata that theories of happiness ought to satisfy. The theory of happiness falls within the province of ethics. It should, however, be viewed as autonomous and not merely secondary to moral theory.     

Effects of frequency on visual word recognition tasks: where are they?

Compared the effect of frequency on lexical decision time (LDT) with that on reaction time (RT) in four other tasks, for the same words and subjects. Exp. 1 yielded an effect on semantic categorization RT (person vs. thing) similar in size and form to the effect on LDT. Exp. 2 yielded a substantial effect for syntactic categorization (noun vs. adjective), although weaker than the effect on LDT. In Exp. 3, the effect on naming RT for stress-final disyllabic words was identical to that on LDT, whereas the effect for stress-initial words was weaker. Exp. 4 showed no effect of frequency on delayed naming RT. The data undermine recent arguments for a (mainly) postidentification task-specific locus of frequency effects but are compatible with the older assumption (also characteristic of new PDP learning models) that lexical identification is a major locus of frequency effects (perhaps together with retrieval of meaning or phonology). But effects at that locus may be masked or diluted by other processes.     

Effects of accenting and regularity on the detection of temporal deviations: does regularity facilitate performance?

In an experiment on the effect of intensity accents on the perception of time intervals between tones, H. G. Tekman (2001) found that the regular placement of deviant time intervals in short sequences of tones reduced detection, especially if intensity accents marked the deviant time intervals. That was the opposite of what one would have expected on the basis of the dynamic attending theory of M. R. Jones (1976). The effect might have occurred because temporally deviant tones create cumulative onset shifts that affect all the subsequent tones. If the deviations were randomly placed, then they could follow each other in close succession and change the local tempo. In the present study, the changes of local tempo, which might have acted as a cue for the detection of temporal deviations in the random sequences, were eliminated by compensating for deviant time intervals with equal deviations in the opposite direction in the interval that followed. That change in the stimuli eliminated the negative main effect of regularity, and the accenting interacted with regularity in favor of detection in the regular sequences. However, a simple advantage of regular over random sequences was not observed. The author discusses possible reasons for the lack of a facilitatory effect of regularity.     

What's in a picture? The impact of face-ism on trait attribution

Previous research indicated a ‘face-ism’ bias in media depictions of men and women: me media tend to represent men with their faces, whereas women's depictions include larger parts of their bodies, rendering their faces less prominent. To explore the impact of facial prominence on impression formation, male and female subjects received either full-body or portrait-style photographs, made from the same negatives, of male and female stimulus persons of different likeability. Male and female subjects evaluated all stimulus persons as more competent (intelligent, assertive, ambitious, etc.) if presented with a high (portrait) rather than a low (full-body photograph) degree of facial prominence. This main effect of facial prominence was not qualified by interaction effects with any of the other variables. PIUS, the media's face-ism bias is likely to contribute to a perception of men as more competent than women. In addition, female but not male subjects also evaluated stimulus persons as more expressive and likeable under conditions of high facial prominence, reflecting a global positive effect of facial prominence.     

What do employers want of counsellors and counseling training?

Abstract

A Psychotherapy and Counselling Network, funded by the Department for Education and Employment, was researching employment and training of therapists and counsellors during the period September 1996 to April 1998. Its main task was examining the relevance of current psychotherapy and counselling training, as perceived by the courses, by the graduates and by the employers of psychotherapists and counsellors. This article summarizes the work carried out in the project, drawing particular attention to what employers might be looking for when they interview candidates for counsellor and psychotherapist posts.     

What to do with a forecast?

In the literature one finds two non-equivalent responses to forecasts; deference and updating. Herein it is demonstrated that, under certain conditions, both responses are entirely determined by one’s beliefs as regards the calibration of the forecaster. Further it is argued that the choice as to whether to defer to, or update on, a forecast is determined by the aim of the recipient of that forecast. If the aim of the recipient is to match their credence with the prevailing objective chances, they should defer to the forecast; if it is to maximize the veritistic value of their beliefs, they should update on the forecast.     

Does a Truck Driver See What a Nurse Sees? The Effects of Occupation Type on Perceptions of Sexual Harassment

Previous researchers have demonstrated differential prevalence of harassment of men and women in men’s traditional, women’s traditional, and neutral occupation types, but they have not looked at differences in harassment judgments among these occupations. Our hypotheses rely on the assumption that people who have observed frequent sexual harassment of others in their work environments react differently to new cases than do those who have witnessed fewer of these episodes in the past. Participants watched videos of two cases and made judgments about the presence or absence of sexual harassment. We categorized the participants based on their occupations—men’s traditional, women’s traditional, and neutral, and compared responses among groups. A gender by occupation type interaction emerged. Men in men’s traditional occupation types provided the highest ratings of harassment, followed by men in neutral occupations; men in women’s traditional occupation types provided the lowest ratings. Conversely, women in women’s traditional occupations provided the highest ratings of harassment, followed by women in neutral occupations; women in men’s traditional occupations provided the lowest ratings of sexual harassment.     

When do irrelevant visual stimuli impair processing of identical targets?

Three experiments investigated whether the repeated-letter inferiority effect (RLIE) and repetition blindness (RB) are identical phenomena or not and how the RLIE can be reconciled with the flanker compatibility effect (FCE). Participants reported a masked target and ignored an unmasked distractor. We manipulated the type of distractor (identical, alternative target, or neutral), the order of presenting distractor and target, and the predictability of target location. When distractors preceded the targets, distractors identical to the target always caused deficits in target processing (i.e., RB). With simultaneous presentation, identical distractors caused deficits (i.e., an RLIE) for unpredictable target locations only. Yet the RLIE was significantly smaller than RB. This result suggests that simultaneously presented stimuli are identified serially, in random order, if target position is unpredictable. As a result, RB arises only in the 50% of all trials with identical distractors in which the distractor is identified before the target. With simultaneous presentation and predictable target location, however, parallel processing of targets and distractors was possible that gave rise to an FCE in recognition accuracy. Analyses of false alarm rates revealed no evidence of significant response biases.
