But the approaches that work will probably differ according to personality.<br \/>\nThis column considers personality in relation to concentration through the Uchida-Kraepelin Test.<\/p>\n<h3>First, what is concentration?<\/h3>\n<p>The Japanese dictionary K\u014djien defines concentration as the power to sustain awareness or attention directed toward a particular thing.<br \/>\nLooking up the word for \u201cpower\u201d gives several meanings, including \u201c\u2461 spirit, mental strength, perseverance, mental energy\u201d and \u201c\u2462 ability, capacity, competence.\u201d<br \/>\nFor this column, let us therefore define concentration as \u201cthe mental strength, perseverance, or ability to sustain awareness or attention directed toward a particular thing.\u201d<\/p>\n<h3>Does concentrating require effort?<\/h3>\n<p>To someone who thinks, \u201cI cannot concentrate even when I try,\u201d or \u201cI lose concentration straight away,\u201d effort may seem essential to concentration.<br \/>\nHowever, examining many Uchida-Kraepelin Test sheets reveals quite a few people who appear to enter or maintain a focused state naturally. So effort does not seem to be essential in every case.<\/p>\n<p>For example, among the <a href=\"https:\/\/adc-japan.com\/uk\/en\/tips-en\/12278.html\">five traits related to behavior and personality<\/a> shown in the Uchida-Kraepelin Test Judgment, people with low Sensitivity (often also with low Flexibility) are frequently observed to show the following tendencies in everyday behavior.<\/p>\n<ul>\n<li>When expressed as a merit, they are calm and composed in their actions. Their mood varies little, and they deliver stable performance.<\/li>\n<li>When expressed as a demerit, they cannot readily adjust their pace flexibly to surrounding circumstances. They may give an impression of indifference or limited receptiveness.<\/li>\n<\/ul>\n<p>A mechanism of \u201cbecoming focused without being aware of it\u201d seems to underlie these tendencies.<br \/>\nOne possible explanation of the clinical observations above would be as follows.<\/p>\n<ul>\n<li>As a merit, becoming focused unconsciously may make their actions calm and composed. The same unconscious focus may explain both the limited variation in mood and their stable performance.<\/li>\n<li>As a demerit, becoming focused unconsciously may make it difficult to adjust their pace flexibly to surrounding circumstances. It may also explain why they sometimes appear indifferent or less receptive.<\/li>\n<\/ul>\n<p>People of this type do not seem to need effort to maintain a focused state.<\/p>\n<p>That may sound enviable to those who feel they cannot concentrate. Yet looking at the demerits reveals another side.<\/p>\n<h3>Effort is needed when switching between states of concentration<\/h3>\n<p>The demerits above suggest that people who become focused unconsciously find it difficult to deliberately disengage or to redirect their focus to what is required. They may be less skilled at doing so, or may not feel inclined to do so.<br \/>\nIn other words, just as someone who has difficulty concentrating needs effort to focus, someone who becomes focused unconsciously may need effort to come out of that state.<\/p>\n<table class=\"uk-focus-diagram\" style=\"max-width:600px;width:100%;background:#e7e7e7;text-align:center;table-layout:fixed;\">\n<tbody>\n<tr>\n<td><\/td>\n<td style=\"background:#5b9bd5;color:#fff;border-radius:12px;padding:12px;\">Unconsciously focused<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td style=\"color:#79ae46;font-size:32px;\">&#x2197;&#x2199;<\/td>\n<td style=\"padding:10px;\">The transitions that require effort differ from person to person.<\/td>\n<td style=\"color:#5b9bd5;font-size:32px;\">&#x2196;&#x2198;<\/td>\n<\/tr>\n<tr>\n<td style=\"background:#79ae46;color:#fff;border-radius:12px;padding:12px;\">Not focused<\/td>\n<td style=\"color:#48bf8e;font-size:32px;\">&#x2194;<\/td>\n<td style=\"background:#48bf8e;color:#fff;border-radius:12px;padding:12px;\">Deliberately focused<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The tendency to become focused unconsciously is also seen in people with low Adaptability and high Resistance\u2014in other words, those whose working curve rises toward the right.<br \/>\nHowever, the way concentration develops differs between people with low Sensitivity and those with a rising working curve.<br \/>\nPeople with low Sensitivity are often naturally focused in everyday life. In contrast, those with a rising working curve tend to become more and more focused as time passes after starting something. Becoming absorbed, engrossed, or single-minded may be a clearer description.<\/p>\n<p>People with medium to high Adaptability tend to find it easier to enter a deliberately focused state. The Uchida-Kraepelin Test has two 15-minute working periods separated by a break. For many examinees, workload is highest during the first one to three minutes of both halves.<br \/>\nThis is attributed to volitional tension: deliberate concentration is directly reflected in an increase in workload.<\/p>\n<p>However, the higher Adaptability is, the larger the difference between the initial workload and the workload thereafter tends to become. Workload visibly falls over time, suggesting that concentration may not be sustained for very long.<\/p>\n<p>People with high Flexibility also seem able to concentrate deliberately when they are in good condition. Because their mental state changes readily, however, they may find it difficult to do so consistently.<\/p>\n<p>Just as focused states appear to include both unconscious and deliberate focus, unfocused states also seem to include two forms: being relaxed and being oversensitive.<\/p>\n<p>People with high Adaptability or Flexibility seem to relax naturally when their concentration ends.<\/p>\n<p>People with high Sensitivity are often in an oversensitive state in everyday life. This could be described as not concentrating on one particular thing while maintaining tension in readiness for unexpected events. That may explain why they are often described as observant at work or school.<\/p>\n<h4>Where to direct effort, according to type<\/h4>\n<p>The following advice for concentrating efficiently by type is based on the discussion above.<br \/>\nAdaptability \u00d7 Flexibility \u00d7 Sensitivity \u00d7 Resistance appear in combination.<br \/>\nUnderstanding your own type, or those of your staff and team members, may help you manage concentration more effectively.<\/p>\n<div class=\"uk-advice-table\" tabindex=\"0\" role=\"region\" aria-label=\"Where to direct effort, according to type\" style=\"max-width:100%;overflow-x:auto;\">\n<table style=\"min-width:600px;width:100%;\">\n<tbody>\n<tr>\n<td width=\"10%\"><\/td>\n<th style=\"vertical-align: middle; text-align: center;\" width=\"45%\">Low trend<\/th>\n<th style=\"vertical-align: middle; text-align: center;\" width=\"45%\">High trend<\/th>\n<\/tr>\n<tr>\n<th style=\"vertical-align: middle; text-align: center;\">Adaptability<\/th>\n<td style=\"vertical-align: top;\"><img decoding=\"async\" class=\"size-full wp-image-7168 aligncenter\" src=\"https:\/\/adc-japan.com\/uk\/wp-content\/uploads\/2021\/02\/adp-l.png\" alt=\"Working-curve example showing low Adaptability\" width=\"157\" height=\"133\" \/><\/p>\n<p>Changing the current state is difficult.<br \/>\nEven if you try to force yourself to start something, getting moving may be hard.
