A fundamental assumption of theories decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face error, adapt to changing circumstances. Is this always case? We investigated relation intention, choice, introspection. Participants made choices presented pairs on basis attractiveness, while covertly manipulated relationship choice outcome they experienced. failed notice conspicuous their intended were with, nevertheless offering introspectively...

However, given the mechanism stochastic resonance, a certain amount noise can benefit We investigate performance in noisy environments relation neurocomputational model attention deficit hyperactivity disorder (ADHD) and dopamine.

Noise is typically conceived of as being detrimental for cognitive performance; however, a recent computational model based on the concepts stochastic resonance and dopamine related internal noise postulates that moderate amount auditive benefit individuals in hypodopaminergic states. On basis this we predicted inattentive children would be enhanced by adding background white while attentive children's performance deteriorate. Fifty-one secondary school pupils carried out an episodic verbal...

Psychological constructs, such as emotions, thoughts, and attitudes are often measured by asking individuals to reply questions using closed-ended numerical rating scales. However, when people about their state of mind in a natural context ("How you?"), we receive open-ended answers words ("Fine happy!") not numbers ("7") or categories ("A lot"). Nevertheless, date it has been difficult objectively quantify responses questions. We develop an approach which the analyzed language processing...

Background: Subjective well-being refers to the extent which a person believes or feels that her life is going well. It considered as one of best available proxies for broader, more canonical form well-being. For over 30 years, important distinction in conceptualization subjective contrast between affective evaluations biological emotional reactions and cognitive one's relation psychologically self-imposed ideal. More recently, researchers have suggested addition harmony life, comprising...

We show that using a recent break-through in artificial intelligence -transformers-, psychological assessments from text-responses can approach theoretical upper limits accuracy, converging with standard rating scales. Text-responses use people's primary form of communication -natural language- and have been suggested as more ecologically-valid response format than closed-ended scales dominate social science. However, previous language analysis techniques left gap between how accurately they...

Abstract Four studies developed and validated two dictionaries to capture agentic communal expressions in natural language. Their development followed the Linguistic Inquiry Word Count ( LIWC ) approach (Study 1) we tested their validity with frequency‐based analyses semantic similarity measures. The newly Agency Communion were aligned categories related agency communion 2), corresponded subjective ratings 3), confirming convergent validity. Very low or absent correspondence between proposed...

Subjective Well-Being (SWB) is usually conceptualized in terms of an affective (i.e., judgements biological emotional reactions and experiences) a cognitive component life satisfaction relation to psychological self-imposed ideal). Recently, researchers have suggested that harmony can replace or at least complement the SWB. Here, however, we go beyond suggestion propose should be seen as SWB's social since it sense balance between individual world around her-a process comprises acceptance,...

The phenomenon of change blindness has received a great deal attention during the last decade, but very few experiments have examined effects subjective importance visual stimuli under study. We addressed this question in series studies by introducing choice as critical variable detection (see Johansson, Hall, Sikström, & Olsson, 2005, Tärning, 2006). In present study, participants were asked to choose which two pictures they found more attractive. For we used both pairs abstract patterns...

ABSTRACT Choice blindness is the finding that participants both often fail to notice mismatches between their decisions and outcome of choice and, in addition, endorse opposite chosen alternative. But do these preference reversals also carry over future choices ratings? To investigate this question, we gave task choosing which a pair faces they found most attractive. Unknown them, sometimes used card trick exchange one face for other. Both decision theory common sense strongly suggest people...

Background Closed-ended rating scales are the most used response format for researchers and clinicians to quantify mental states, whereas in natural contexts people communicate with language. The reason using such is that they typically argued be more precise measuring constructs; however, respondents’ views as what best communicates states frequently ignored, which important making them comply assessment.

Abstract Middle aged adults experience depression and anxiety differently than younger adults. Age may affect life circumstances, depending on accessibility of social connections, jobs, physical health, etc, as these factors influence the prevalence symptomatology. Depression are typically measured using rating scales; however, recent research suggests that such symptoms can be assessed by open-ended questions analysed question-based computational language assessments (QCLA). Here, we study...

BackgroundHappiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings emotions) judgements a self-imposed ideal cognitive life satisfaction). Recent research has established these two dimensions primary parts higher order factor. However, theoretical, conceptual, empirical work suggest that harmony in their sense balance capacity to behave adapt with both acceptance...
