How to know one’s experiences transparently

Philosophical Studies - I would like to propose a demonstrative transparency model of our immediate, introspective self-knowledge of experiences. It is a model entirely in line with transparency....     

Can one pay attention to a particular color?

In an array of elements whose colors vary can we selectively choose to process all the items of a particular color preferentially in relation to those of another color? We addressed this question by presenting subjects with arrays containing many elements, and recording reaction times to a luminance change of one of the elements. Half the elements had one color and the other half another color--the spatial distribution being random. In two tasks--a simple detection of this change or a choice reaction time to the polarity of the change--we found that reaction times were independent of the number of items in the array. Cuing the subjects as to the color of the target item had no significant influence on the detection task, but subjects were faster if cued for the discrimination task. A further experiment replicated these findings and examined possible costs and benefits. Our final experiment separated the roles of attentional guidance and postattentional processes by having subjects judge the orientation of the target element and varying the magnitude of the target flash that defined which element was the target. We found that this judgment was also affected by color cuing, and that the size of the effect interacted with the flash strength, suggesting that color cuing has its influence at the stage of attentional guidance. We conclude that subjects can selectively attend to items on the basis of color given the appropriate task and stimulus dynamics.     

The speed of metacognition: Taking time to get to know one’s structural knowledge

The time course of different metacognitive experiences of knowledge was investigated using artificial grammar learning. Experiment 1 revealed that when participants are aware of the basis of their judgments (conscious structural knowledge) decisions are made most rapidly, followed by decisions made with conscious judgment but without conscious knowledge of underlying structure (unconscious structural knowledge), and guess responses (unconscious judgment knowledge) were made most slowly, even when controlling for differences in confidence and accuracy. In experiment 2, short response deadlines decreased the accuracy of unconscious but not conscious structural knowledge. Conversely, the deadline decreased the proportion of conscious structural knowledge in favour of guessing. Unconscious structural knowledge can be applied rapidly but becomes more reliable with additional metacognitive processing time whereas conscious structural knowledge is an all-or-nothing response that cannot always be applied rapidly. These dissociations corroborate quite separate theories of recognition (dual-process) and metacognition (higher order thought and cross-order integration).     

Reactions to the fate of one’s brain-child after its disclosure

After generating an idea we believe is original, we want it to be credited as original and receive recognition for it. So, we would be upset if its originality were questioned, or if our link to that intellectual self-extension were threatened, and we would cope with self-protective strategies. This rationale prompted an experiment with seventy-five female undergraduates. They (P) were to imagine drafting a paper for submission to a national creativity fair proposing a novel method for determining the structure of things, but then decided against submitting it. Fellow-participant, O, learning of P's decision to withdraw, borrows P’s draft. Later, P submits a revised, retitled draft that, unfortunately, goes astray. Still later P discovers that O, without P's knowledge and consent, submitted a copy of P’s original draft to the fair, listing O’s name, both names, or P’s name as author(s), and that the idea was or was not judged as original. Origination and recognition credit allocation had predicted effects on P’s emotional reaction, evaluation of the judges’competence, and of O’s trustworthiness. Unexpect-edly low self-evaluated creativity and sociability, and low desire for future collabora-tion, were obtained when recognition went to P and O jointly. We discuss the applica-bility of belief agreement-attraction and cognitive balance models, of imitation as flattery, of self-esteem as a moderator, and whether our results are culture-bound. Finally, we note how the reactions hint at conflict between inclinations toward altru-ism versus narcissistic self-interest when it comes to sharing one’s self-generated intellectual products with others.     

Desire to change one’s multimodality and its relationship to the use of different transport means

Using data collected from French employees of a transportation institute and residents of the US San Francisco Bay Area, we operationalize a segmentation of mobility patterns based on objective, subjective, and desired amounts of mobility by various modes and overall. We especially focus on the degree of multimodality in an individual’s current modal mix and desired changes to that mix through the use of a “multimodality index”. The clusters that result showed some similarities and some differences across countries, where the latter are likely due to disparities in the sampling strategies and in the land use/transportation/cultural milieux. In both cases, however, the clusters have useful policy implications, enabling us, for example, to distinguish car users who might be inclined to reduce car use and increase transit use from those who are largely content with their current modal baskets.     

Mind-wandering and negative mood: Does one thing really lead to another?

Mind-wandering is closely connected with negative mood. Whether negative mood is a cause or consequence of mind-wandering remains an important, unresolved, issue. We sought to clarify the direction of this relationship by measuring mood before and after mind-wandering. We also measured the affective content, time-orientation and relevance of mind-wandering to current concerns to explore whether the link between mind-wandering and negative mood might be explained by these characteristics. A novel experience-sampling technique with smartphone application prompted participants to answer questions about mind-wandering and mood across 7 days. While sadness tended to precede mind-wandering, mind-wandering itself was not associated with later mood and only predicted feeling worse if its content was negative. We also found prior sadness predicted retrospective mind-wandering, and prior negative mood predicted mind-wandering to current concerns. Our findings provide new insight into how mood and mind-wandering relate but suggest mind-wandering is not inherently detrimental to well-being.     

Two strings to choose from: do ravens pull the easier one?

There are simple co-occurrences as well as functional relationships between events. One may assume that animals detect and use causation rather than mere co-variation. However, understanding causation often requires concepts of hidden forces. In string pulling, obstacles may hamper the access to food. Here, I studied whether ravens have an abstract concept of effort. First, in a competitive situation, ravens (Corvus corax) could choose one out of two strings. The strings differed in whether they were baited with meat and in how far away the meat was. Ravens pulled mainly the string containing meat and where the meat was nearer to the perch, respectively. Second, ravens could choose between two strings that had either a functional obstacle or a non-functional obstacle. Optimal performance required the integration of at least two cues: object and height. In 5 ravens, the model that best matched behaviour took into account only that meat was on a string, ignoring the obstacle. However, 2 ravens' performance was best explained by a model that took into account both an object's identity (meat or wood) and its height on the string. Third, one string out of two was loaded with a heavy meat piece. In this overloaded string condition, 5 out of 7 ravens did not try to pull the heavy meat piece but went straight for pulling the smaller piece. The pattern of results indicated that ravens can judge the effort required to pull a string.     

What if I am the one? Measuring individual differences in emotional sensitivity to probability and emotional reactivity to possibility

Current theories of risk perception point to the powerful role of emotion and the neglect of probabilistic information in the face of risk, but these tendencies differ across individuals. We propose a method for measuring individuals' emotional sensitivity to probability to assess how feelings about probabilities, rather than the probabilities themselves, influence decisions. Participants gave affective ratings (worry or excitement) to 14 risky events, each with a specified probability ranging from 1 in 10 to 1 in 10,000,000. For each participant, we regressed these emotional responses against item probabilities, estimating a slope (the degree to which emotional responses change with probability) and an intercept (the emotional reaction to an event with a fixed probability). These two parameters were treated as individual difference scores and included in models predicting reactions to several health risk scenarios. Both emotional sensitivity to probability (slope) and emotional reactivity to possibility (intercept) significantly predicted responses to these scenarios, above and beyond the predictive power of other well‐established individual difference measures.     

Time to make two Koreas one again: Korean Christians’ self-reflection and diakonia duties

ABSTRACT

As the reunification of South and North Korea has increasingly become imminent since the 2018 Pyeongchang Winter Olympics, this article aims to provide a critical reflection on South Korean efforts, including Christianity, and suggests some practical ways forward. Starting with the reunification efforts over the last few decades, barriers and catalysts for the reunification, the article argues that both Koreas, adjacent nations and the international world must make a new effort. Within Korea, Christianity has been a catalyst as well as an obstacle for the reunification. The reunification is an opportunity for both Koreas to co-prosper, and not simply a South Korean opportunity to extend its own wealth. Korean Christianity has a special responsibility to reflect on some mistakes that occurred among foreign mission stakeholders in Korea and within Korean Christianity itself. Most of all, Korean Christianity ought to reimagine itself in the lead-up to the reunification and practise diakonia towards fellow North Koreans. A systematic cooperation among some exemplary services for North Korean defectors and the marginalised is a preparatory practice, in addition to diakonia education and implementation within the church and the broader community.     

Commitment to one’s spouse as a predictor of marital quality among older couples

The present study examined the relationships between several independent variables (ego development, commitment to the spouse, length of marriage, church attendance, and sex of subject) and three marital quality variables (marriage problems, expression of love, and dyadic adjustment) in a community sample of 72 married couples age 50 and up. Commitment to the spouse was the strongest and most consistent predictor of marital quality; commitment was negatively related to marriage problems and positively related to expression of love and dyadic adjustment. The other independent variables were generally unrelated to marital quality.     

Who can spot a potential problem gambler? Testing “it takes one to know one” and acquaintanceship effects in a university student population

How easy is it for individuals to detect low to moderate levels of problem gambling tendencies in others? Are individuals who have problem gambling tendencies themselves, or are close relationship partners, more accurate judges? We examine these questions in two studies involving a total of 336 interacting dyads drawn largely from a university student population. In Study 1 all pairs were strangers, whereas in Study 2 approximately half of the pairs were close. After the “judge” observed the “target” complete a gambling task, the dyad had a face-to-face discussion, with topics including favorite pastimes and personal weaknesses. Judges estimated the target's problem gambling tendencies, and both judges and targets self-reported their own gambling tendencies. There was evidence of modest, albeit somewhat inconsistent, accuracy in individuals’ judgments of the other person's problem gambling tendencies, but no “it takes one to know one” or acquaintanceship effects were apparent. Results also indicated that judges evidenced a projection bias, whereby they saw the target as similar to themselves, especially within close pairs. These results reveal that even after minimal interaction with a stranger individuals can be able to judge the person's gambling tendencies with some accuracy. At the same time, our findings indicating that close others and those with problem gambling tendencies themselves are not more or less tuned in to the early signs of a problem than anyone else suggest that it would be inappropriate to be especially convinced by—or skeptical of—these individuals’ judgments.     

Executive function tests in early‐onset psychosis: which one to choose?

People with schizophrenia exhibit executive functioning deficits, an area well investigated in the adult onset schizophrenia (AOS) group, but far less so in early-onset schizophrenia (EOS). Since EOS in general seems to exhibit poorer cognitive functions and is clinically more compromised than AOS, choice of efficient and sensitive assessment measures is not necessarily the same within the two groups. The MATRICS Consensus Cognitive Battery was developed for adults when studying treatment effects and uses Mazes (Neuropsychological Assessment Battery [NAB]) to assess executive functioning. We tested 31 adolescents with schizophrenia spectrum disorders and 66 healthy controls in order to examine how Mazes compares to two other commonly used tests to measure executive functioning, D-KEFS Color Word Interference Test (Stroop) and the Wisconsin Card Sorting Test (WCST). Significant discriminating power was found for all three measures. Patients performed 0.8-1.5 SD below controls with Stroop as the most sensitive measure, followed by Mazes and WCST. Mazes was selected by the MATRICS to assess treatment effects in AOS and is shown to be able. We find the instrument also able to separate adolescent patients from controls and thus, it appears a sensible choice in clinical settings. If a more elaborated neuropsychological evaluation of the executive functioning domain is needed, Stroop should be considered a complementary test.     

One world,one environment,one vision: are we close to achieving this? An exploratory study of consumer environmental behaviour across three countries

The environment as an issue has been central to a number of conferences and debates held worldwide. This indicates the growing concern regarding environmental issues on the part of various nations. It is apparent that both public support and political efforts are required to halt environmental deterioration. Members of the public need to display a change in attitude and governments need policies and strategies to channel this change in appropriate directions. The present study concentrates on the aspect of public awareness and how this translates to their purchase of environmentally friendly products. The theoretical framework incorporates respondents from three countries. The main aim is to investigate differences in public awareness and behaviour based on individual variables, such as Cognitive style and Involvement, and broad factors, such as the economic and developmental stages of the countries included in the sample. Data has been collected from a sample of 132 respondents. The results indicate that the attitudes and behaviour of UK respondents are generally non‐committal, whereas the sample from India displays a more involved attitude, which is reflected in their purchasing behaviour. The ‘availability’ and the ‘price’ of environmentally friendly products have been identified as the most significant issues common to India, Greece and the UK. Cognitive style analysis indicates that innovators are responsible for generating a range of qualitative differences, whereas the differences highlighted by Involvement are quantitative in nature.

Is it possible to prepare the second component of a movement before the first one?

Experiment 1 utilized a choice reaction time paradigm to examine whether advance information about the second component of a movement has similar effects upon movement initiation and execution as advance information about the first component. Four stimuli were assigned to four goal keys. Subjects responded with the index finger of their preferred hand. They had to press on of two intermediate keys before pressing the assigned stimulus goal key. Advance information signaled one pair of goal keys in such a way that either the first or the second movement component was unequivocally specified before the response signal appeared. Shorter reaction times resulted when the first component was precued. Further control conditions showed that advance information about the second movement component could not be utilized for movement preparation. Experiment 2 ruled out a perceptual interpretation of this effect. Experiment 3 showed that preparation time for two-component movements are longer than for one-component movements. The study permits the conclusions that speeded two-component movements are controlled by motor programs and that advance information about the first movement component is required before the second movement component can be programmed.     

Two boys—one event

The background of this paper is an investigation of child survivors from the Holocaust; in a study of interviews of these survivors, it could be concluded that past traumatic experiences are recovered not as memories (in the usual sense of the word), but as affects invading the present. Accordingly, affects seem to tell the story of the past traumatic experiences. In this paper, the author investigates two accounts (separately told by two survivors) of the same event in the Kielce ghetto. The two accounts present similarities, but also differences, and the author discusses these in relation to the concepts of historical and narrative truth, as well as in relation to construction and reconstruction, concluding that the interviews give a sketch of how the experiences have become idiosyncratically registered in the minds of the interviewees.     

Are families supported to come to terms with an autism diagnosis? A service evaluation of referrals to family therapy for young people with autism in one NHS trust

Young people with autism are increasingly being referred for family therapy (FT) owing to impaired family functioning, but few studies have investigated the support families receive following a diagnosis through specific NHS Trusts. This study examined (1) the proportion of autism cases referred for FT in one Trust and (2) the post-diagnostic support families received. Participants (n = 144; 9.5–19.3 years) were FT referrals between 2019–2020. Autism diagnostic status and the support families received from FT, from the neurodevelopmental (ND) service which specialises in autism, and for co-occurring conditions [e.g., cognitive behavioural therapy (CBT)] was extracted retrospectively from routine data. Forty FT referrals met autism criteria: several families did not receive FT; few were provided with support from the ND service; and if CBT was offered, no adaptations for autism were noted. Families received insufficient support following a diagnosis through this Trust. Implications include improving post-diagnostic support for families in practice.     

There is more than one level in color naming — A reply to Zollinger (1984)

Summary It is argued that the structure of the Munsell solid is not sufficient to explain the evolution of color terms as Zollinger (1984) has argued. A manifold model of color perception is described with a local metric structure of discriminability and a global categorical structure. This model elucidates the interdependency of the different levels of constraints on color naming and permits the integration of experimental results which cannot be explained in the model underlying Zollinger's (1984) color-metric argument for the emergence of turquoise.
