Both Earlier Times and the Future Are “Front”: The Distinction Between Time‐ and Ego‐Reference‐Points in Mandarin Speakers’ Temporal Representation

Mandarin speakers, like most other language speakers around the world, use spatial terms to talk about time. However, the direction of their mental temporal representation along the front‐back axis remains controversial because they use the spatial term “front” to refer to both earlier times (e.g., front‐year means “the year before last”) and the future (e.g., front‐road means “prospect”). Although the linguistic distinction between time‐ and ego‐reference‐point spatiotemporal metaphors in Mandarin suggests a promising clarification of the above controversy, there is little empirical evidence verifying this distinction. In this study, Mandarin speakers’ time‐ and ego‐reference‐point temporal representations on three axes (i.e., sagittal, lateral, and vertical) were separately examined through two tasks. In a time‐reference‐point task, Mandarin speakers judged whether the time point of the second picture was earlier or later than the time point of the first picture, while in an ego‐reference‐point task, they judged whether an event or phase had happened in the past or would happen in the future. The results indicate that Mandarin speakers construe an earlier‐times‐in‐front‐of‐later‐times temporal sequence and adopt the front‐to‐the‐future orientation.     

Stroke me for longer this touch feels too short: The effect of pleasant touch on temporal perception

Negative, painful, somatosensory stimulation lengthens the perceived duration of time. However, to date, no research has explored the influence of positive, pleasant, somatosensory stimulation on temporal perception. Here we asked whether gentle stroking touch influences perceptions of duration. Pleasant (gentle) and mildly unpleasant (rough) tactile stimulation was delivered whilst participants estimated the duration of a neutral visual stimulus. Pleasant touch resulted in shorter estimates of duration than unpleasant touch. There was no difference in duration perception in the unpleasant and control conditions. Taken together with the results of previous research (Ogden, Moore, Redfern, & McGlone, 2015), the results of this study suggest that pleasant and painful somatosensory stimulation have opposing effects on temporal perception, and additionally that pleasant touch can alter aspects of perceptual and attentional processing outside the purely affective domain.     

The development of perceptual sensitivity to second-order facial relations in children

This study investigated children’s perceptual ability to process second-order facial relations. In total, 78 children in three age groups (7, 9, and 11 years) and 28 adults were asked to say whether the eyes were the same distance apart in two side-by-side faces. The two faces were similar on all points except the space between the eyes, which was either the same or different, with various degrees of difference. The results showed that the smallest eye spacing children were able to discriminate decreased with age. This ability was sensitive to face orientation (upright or upside-down), and this inversion effect increased with age. It is concluded here that, despite early sensitivity to configural/holistic information, the perceptual ability to process second-order relations in faces improves with age and constrains the development of the face recognition ability.     

The future-orientation of memory: Planning as a key component mediating the high levels of recall found with survival processing

In a series of papers, Nairne and colleagues have demonstrated that tasks encouraging participants to judge words for relevance to survival led to better recall than did tasks lacking survival relevance. Klein, Robertson, and Delton (2010) presented data suggesting that the future-directed temporal orientation of the survival task (e.g., planning), rather than survival per se, accounts for the good recall found with the task. In the present studies we manipulated the amount of survival and planning processing encouraged by a set of encoding tasks. Participants performed tasks that encouraged processing stimuli for their relevance to (a) both survival and planning, (b) planning, but not survival, or (c) survival but not planning. We predicted, and found, that recall performance associated with tasks encouraging planning (i.e., survival with planning and planning without survival) should exceed tasks that encouraged survival but not planning (i.e., survival without planning). We draw several conclusions. First, planning is a necessary component of the superior recall found in the survival paradigm. Second, memory, from an evolutionary perspective, is inherently prospective—tailored by natural selection to support future decisions and judgements that cannot be known in advance with certainty.     

The effect of mindfulness meditation on time perception

Research has increasingly focussed on the benefits of meditation in everyday life and performance. Mindfulness in particular improves attention, working memory capacity, and reading comprehension. Given its emphasis on moment-to-moment awareness, we hypothesised that mindfulness meditation would alter time perception. Using a within-subjects design, participants carried out a temporal bisection task, where several probe durations are compared to “short” and “long” standards. Following this, participants either listened to an audiobook or a meditation that focussed on the movement of breath in the body. Finally, participants completed the temporal bisection task for a second time. The control group showed no change after the listening task. However, meditation led to a relative overestimation of durations. Within an internal clock framework, a change in attentional resources can produce longer perceived durations. This meditative effect has wider implications for the use of mindfulness as an everyday practice and a basis for clinical treatment.     

Bias and learning in temporal binding: Intervals between actions and outcomes are compressed by prior bias

It has consistently been shown that agents judge the intervals between their actions and outcomes as compressed in time, an effect named intentional binding. In the present work, we investigated whether this effect is result of prior bias volunteers have about the timing of the consequences of their actions, or if it is due to learning that occurs during the experimental session. Volunteers made temporal estimates of the interval between their action and target onset (Action conditions), or between two events (No-Action conditions). Our results show that temporal estimates become shorter throughout each experimental block in both conditions. Moreover, we found that observers judged intervals between action and outcomes as shorter even in very early trials of each block. To quantify the decrease of temporal judgments in experimental blocks, exponential functions were fitted to participants’ temporal judgments. The fitted parameters suggest that observers had different prior biases as to intervals between events in which action was involved. These findings suggest that prior bias might play a more important role in this effect than calibration-type learning processes.     

Toward an ethic of the biosphere

This article consists of three parts. The first explores the relation between paradox, de-paradoxication, and time, which I hold to be a relatively unattended yet very important tandem of concepts in Luhmann's work (Luhmann, 1993, 1995; Rasch, 2000). The second part will try to theoretically think through (de-paradoxicalize) a conundrum of present time: globalization and its opponents. In the third and last part, I briefly explore the paradox of conscious evolution, taking into account the specifics of the relations between social systems of communication and individual psychic systems in Luhmann's theory.     

The effects of trait and state anxiety on attention to emotional images: An eye-tracking study

Attentional biases for threatening stimuli have been implicated in the development of anxiety disorders. However, little is known about the relative influences of trait and state anxiety on attentional biases. This study examined the effects of trait and state anxiety on attention to emotional images. Low, mid, and high trait anxious participants completed two trial blocks of an eye-tracking task. Participants viewed image pairs consisting of one emotional (threatening or positive) and one neutral image while their eye movements were recorded. Between trial blocks, participants underwent an anxiety induction. Primary analyses examined the effects of trait and state anxiety on the proportion of viewing time on emotional versus neutral images. State anxiety was associated with increased attention to threatening images for participants, regardless of trait anxiety. Furthermore, when in a state of anxiety, relative to a baseline condition, durations of initial gaze and average fixation were longer on threat versus neutral images. These findings were specific to the threatening images; no anxiety-related differences in attention were found with the positive images. The implications of these results for future research, models of anxiety-related information processing, and clinical interventions for anxiety are discussed.     

Time-Based Prospective Memory Performance and Time-Monitoring in Children with ADHD

The current study investigated prospective memory (PM) performance in children with attention deficit/hyperactivity disorder (ADHD) and controls and aimed at exploring possible underlying factors of PM performance. Twenty-two children with ADHD and 39 age- and ability-matched typically developing children performed a computerized time-based PM task. As predicted, children with ADHD had fewer correct PM responses than controls. Neither differences in overall ongoing task performance nor, remarkably, differences in overall frequency and accuracy of time monitoring were found. Exploratory analyses suggest that individual differences in time monitoring in the final interval before target times may be related to PM performance in ADHD.
